Subject: [WATCHDOG] Atmel AT91RM9200 rename.

The new Atmel AT91SAM9261 and AT91SAM9260 processors use a different
internal watchdog peripheral.  This watchdog driver is therefore
AT91RM9200-specific.

This patch renames at91_wdt.c to at91rm9200_wdt.c, and changes the name
of the configuration option.

Subject: [POWERPC] Don't crash on cell with 2 BEs when !CONFIG_NUMA

The SPU code will crash if CONFIG_NUMA is not set and SPUs are found on
a non-0 node. This workaround will ignore those SPEs and just print an
message in the kernel log.

Subject: [POWERPC] Add DOS partition table support to mpc834x_itx_defconfig

The default configuration file for the MPC8349E-mITX reference board,
mpc834x_itx_defconfig, did not include support for DOS partition table types.
This support is necessary because the hard drive that comes with the ITX
is formatted with this partition table type.  Without this config option,
no partitions on the drive can be mounted.

Subject: [POWERPC] Fix IO Window Updates on P2P bridges.

When update_bridge_base() updates the IO window on a PCI-to-PCI
bridge, it fails to zero the upper 16 bits of the base and limit
registers if the window size is less than 64K.  This fixes it.

Subject: [POWERPC] Never panic when taking altivec exceptions from userspace

At the moment we rely on a cpu feature bit or a firmware property to
detect altivec. If we dont have either of these and the cpu does in fact
support altivec we can cause a panic from userspace.

It seems safer to always send a signal if we manage to get an 0xf20
exception from userspace.

During boot we bring up all memory and cpu nodes. Normally a PCI device
will be in one of these online nodes, however in some weird setups it
may not.

We have only seen this in the lab but we may as well check for the case
and fallback to -1 (all nodes).

Subject: [POWERPC] Lazy interrupt disabling for 64-bit machines

This implements a lazy strategy for disabling interrupts.  This means
that local_irq_disable() et al. just clear the 'interrupts are
enabled' flag in the paca.  If an interrupt comes along, the interrupt
entry code notices that interrupts are supposed to be disabled, and
clears the EE bit in SRR1, clears the 'interrupts are hard-enabled'
flag in the paca, and returns.  This means that interrupts only
actually get disabled in the processor when an interrupt comes along.

When interrupts are enabled by local_irq_enable() et al., the code
sets the interrupts-enabled flag in the paca, and then checks whether
interrupts got hard-disabled.  If so, it also sets the EE bit in the
MSR to hard-enable the interrupts.

This has the potential to improve performance, and also makes it
easier to make a kernel that can boot on iSeries and on other 64-bit
machines, since this lazy-disable strategy is very similar to the
soft-disable strategy that iSeries already uses.

This version renames paca->proc_enabled to paca->soft_enabled, and
changes a couple of soft-disables in the kexec code to hard-disables,
which should fix the crash that Michael Ellerman saw.  This doesn't
yet use a reserved CR field for the soft_enabled and hard_enabled
flags.  This applies on top of Stephen Rothwell's patches to make it
possible to build a combined iSeries/other kernel.

Subject: [POWERPC] powerpc: Enable DEEPNAP power savings mode on 970MP

Without this patch, on an idle system I get:

cpu-power-0:21.638
cpu-power-1:27.102
cpu-power-2:29.343
cpu-power-3:25.784
Total: 103.8W

With this patch:

cpu-power-0:11.730
cpu-power-1:17.185
cpu-power-2:18.547
cpu-power-3:17.528
Total: 65.0W

If I lower HZ to 100, I can get it as low as:

cpu-power-0:10.938
cpu-power-1:16.021
cpu-power-2:17.245
cpu-power-3:16.145
Total: 60.2W

Another (older) Quad G5 went from 54W to 39W at HZ=250.

Coming back out of Deep Nap takes 40-70 cycles longer than coming back
from just Nap (which already takes quite a while). I don't think it'll
be a performance issue (interrupt latency on an idle system), but in
case someone does measurements feel free to report them.

Subject: [POWERPC] Remove todc code from ARCH=powerpc

Apparently we've copied the todc drivers, for various RTCs used in
embedded machines from ARCH=ppc to ARCH=powerpc, despite the fact that
it's never used in the latter.  This patch removes it.

If we ever need these drivers (which we probably shouldn't now the RTC
class stuff is in), we can transfer them one by one from ARCH=ppc,
removing from the hideous abomination which is the todc
"infrastructure".

Subject: [PATCH] i386 Time: Avoid PIT SMP lockups

Avoid possible PIT livelock issues seen on SMP systems (and reported by
Andi), by not allowing it as a clocksource on SMP boxes.

However, since the PIT may no longer be present, we have to properly handle
the cases where SMP systems have TSC skew and fall back from the TSC.
Since the PIT isn't there, it would "fall back" to the TSC again.  So this
changes the jiffies rating to 1, and the TSC-bad rating value to 0.

Thus you will get the following behavior priority on i386 systems:

tsc		[if present & stable]
hpet		[if present]
cyclone		[if present]
acpi_pm		[if present]
pit		[if UP]
jiffies

Rather then the current more complicated:
tsc		[if present & stable]
hpet		[if present]
cyclone		[if present]
acpi_pm		[if present]
pit		[if cpus < 4]
tsc		[if present & unstable]
jiffies

Subject: [PATCH] genirq: clean up irq-flow-type naming

Introduce desc->name and eliminate the handle_irq_name() hack.  Add
set_irq_chip_and_handler_name() to set the flow type and name at once.

Perfmon interrupt handler needs to use get_irq_regs() too.

Subject: [IA64] remove unused PAL_CALL_IC_OFF

Linux maps PAL instructions with an ITR, but uses a DTC for PAL data.
Section 11.10.2.1.3, "Making PAL Procedures Calls in Physical or Virtual
Mode," of the SDM (rev 2.2), says we must therefore make all PAL calls
with PSR.ic = 1 so that Linux can handle any TLB faults.

PAL_CALL_IC_OFF is currently unused, and as long as we use the ITR + DTC
strategy, we can't use it.  So remove it.  I also removed the code in
ia64_pal_call_static() that conditionally cleared PSR.ic.

Subject: [IA64] update sn2_defconfig

The current sn2_defconfig is obsolete, in particular the recent ATA
changes are a pain, so here's a patch to get things in sync ... at
least for a day or two :)

Update sn_defconfig to match current community kernel tree.

Subject: [POWERPC] Make sure interrupt enable gets restored properly

The lazy IRQ disable patch missed a couple of places where the
interrupt enable flags need to be restored correctly.  First, we
weren't restoring the paca->hard_enabled flag on interrupt exit.
Instead of saving it on entry, we compute it from the MSR_EE bit
in the MSR we are restoring at exit.  Secondly, the MMU hash miss
code was clearing both paca->soft_enabled and paca->hard_enabled
but not restoring them in the case where hash_page was able to
resolve the miss from the Linux page tables.

Subject: [SPARC64]: Fix PCI memory space root resource on Hummingbird.

For Hummingbird PCI controllers, we should create the root
PCI memory space resource as the full 4GB area, and then
allocate the IOMMU DMA translation window out of there.

The old code just assumed that the IOMMU DMA translation base
to the top of the 4GB area was unusable.  This is not true on
many systems such as SB100 and SB150, where the IOMMU DMA
translation window sits at 0xc0000000->0xdfffffff.

So what would happen is that any device mapped by the firmware
at the top section 0xe0000000->0xffffffff would get remapped
by Linux somewhere else leading to all kinds of problems and
boot failures.

While we're here, report more cases of OBP resource assignment
conflicts.  The only truly valid ones are ROM resource conflicts.

Subject: [POWERPC] More bootwrapper reorganization

More reorganization of the bootwrapper:
- Add dtb section to zImage
- ft_init now called by platform_init
- Pack a flat dt before calling kernel
- Remove size parameter from free
- printf only calls console_ops.write it its not NULL
- Some cleanup

Subject: PCI: Turn pci_fixup_video into generic for embedded VGA

pci_fixup_video turns into generic code because there are many platforms need this fixup
for embedded VGA as well as x86. The Video BIOS integrates into System BIOS on a machine
has embedded VGA although embedded VGA generally don't have PCI ROM. As a result,
embedded VGA need the way that the sysfs rom points to the Video BIOS of System
RAM (0xC0000). PCI-to-PCI Bridge Architecture specification describes the condition whether
or not PCI ROM forwards VGA compatible memory address. fixup_video suits this specification.
Although the Video ROM generally implements in x86 code regardless of platform, some
application such as X Window System can run this code by dosemu86. Therefore,
pci_fixup_video should turn into generic code.

Subject: PCI: optionally sort device lists breadth-first

Problem:
New Dell PowerEdge servers have 2 embedded ethernet ports, which are
labeled NIC1 and NIC2 on the chassis, in the BIOS setup screens, and
in the printed documentation.  Assuming no other add-in ethernet ports
in the system, Linux 2.4 kernels name these eth0 and eth1
respectively.  Many people have come to expect this naming.  Linux 2.6
kernels name these eth1 and eth0 respectively (backwards from
expectations).  I also have reports that various Sun and HP servers
have similar behavior.


Root cause:
Linux 2.4 kernels walk the pci_devices list, which happens to be
sorted in breadth-first order (or pcbios_find_device order on i386,
which most often is breadth-first also).  2.6 kernels have both the
pci_devices list and the pci_bus_type.klist_devices list, the latter
is what is walked at driver load time to match the pci_id tables; this
klist happens to be in depth-first order.

On systems where, for physical routing reasons, NIC1 appears on a
lower bus number than NIC2, but NIC2's bridge is discovered first in
the depth-first ordering, NIC2 will be discovered before NIC1.  If the
list were sorted breadth-first, NIC1 would be discovered before NIC2.

A PowerEdge 1955 system has the following topology which easily
exhibits the difference between depth-first and breadth-first device
lists.

-[0000:00]-+-00.0  Intel Corporation 5000P Chipset Memory Controller Hub
           +-02.0-[0000:03-08]--+-00.0-[0000:04-07]--+-00.0-[0000:05-06]----00.0-[0000:06]----00.0  Broadcom Corporation NetXtreme II BCM5708S Gigabit Ethernet (labeled NIC2, 2.4 kernel name eth1, 2.6 kernel name eth0)
           +-1c.0-[0000:01-02]----00.0-[0000:02]----00.0  Broadcom Corporation NetXtreme II BCM5708S Gigabit Ethernet (labeled NIC1, 2.4 kernel name eth0, 2.6 kernel name eth1)


Other factors, such as device driver load order and the presence of
PCI slots at various points in the bus hierarchy further complicate
this problem; I'm not trying to solve those here, just restore the
device order, and thus basic behavior, that 2.4 kernels had.


Solution:

The solution can come in multiple steps.

Suggested fix #1: kernel
Patch below optionally sorts the two device lists into breadth-first
ordering to maintain compatibility with 2.4 kernels.  It adds two new
command line options:
  pci=bfsort
  pci=nobfsort
to force the sort order, or not, as you wish.  It also adds DMI checks
for the specific Dell systems which exhibit "backwards" ordering, to
make them "right".


Suggested fix #2: udev rules from userland
Many people also have the expectation that embedded NICs are always
discovered before add-in NICs (which this patch does not try to do).
Using the PCI IRQ Routing Table provided by system BIOS, it's easy to
determine which PCI devices are embedded, or if add-in, which PCI slot
they're in.  I'm working on a tool that would allow udev to name
ethernet devices in ascending embedded, slot 1 .. slot N order,
subsort by PCI bus/dev/fn breadth-first.  It'll be possible to use it
independent of udev as well for those distributions that don't use
udev in their installers.

Suggested fix #3: system board routing rules
One can constrain the system board layout to put NIC1 ahead of NIC2
regardless of breadth-first or depth-first discovery order.  This adds
a significant level of complexity to board routing, and may not be
possible in all instances (witness the above systems from several
major manufacturers).  I don't want to encourage this particular train
of thought too far, at the expense of not doing #1 or #2 above.


Feedback appreciated.  Patch tested on a Dell PowerEdge 1955 blade
with 2.6.18.

You'll also note I took some liberty and temporarily break the klist
abstraction to simplify and speed up the sort algorithm.  I think
that's both safe and appropriate in this instance.

Subject: sh: Proper show_stack/show_trace() implementation.

This splits out some of the previous show_stack() implementation which
was mostly doing the show_trace() work without actually dumping any of
the stack contents. This now gets split in to two sections, where we
do the fetching of the stack pointer and subsequent stack dumping in
show_stack(), while moving the call trace in to show_trace().

From 082c44d20eb4c6c4aa60ae7429ea184854cb0610 Mon Sep 17 00:00:00 2001
From: Paul Mundt <lethal@linux-sh.org>
Date: Thu, 19 Oct 2006 16:16:18 +0900
Subject: sh: Cleanup board header directories.

Now with the ide.h mess sorted out, most of these boards
don't need their own directory. Move the headers out, and
update the driver paths.

Signed-off-by: Paul Mundt <lethal@linux-sh.org>

From 1f666587dbf6bc660b23d8dd8abb6c572ce3eae5 Mon Sep 17 00:00:00 2001
From: Paul Mundt <lethal@linux-sh.org>
Date: Thu, 19 Oct 2006 16:20:25 +0900
Subject: sh: Fix exception_handling_table alignment.

With the recent change ripping out interrupt_table, explicit
padding of the table was missing, causing bad things to happen
when manually inserting handlers in to the table. This problem
particularly showed up in relation to do_fpu_state_restore()
which was inserted quite deeply in to the table and ended up
scribbling over a slab object.

Subject: [MIPS] Use kallsyms_lookup_size_offset() instead of kallsyms_lookup()

This new routine doesn't lookup for symbol names. So we needn't
to pass any char buffers or pointer since we don't care about
names.

Subject: [MIPS] Fix O32 personality(2) call with 0xffffffff argument.

A sign extension bug did result in sys_personality being invoked with a
0xffffffffffffffffUL argument, so querying the current personality didn't
work.

Subject: [MIPS] save_context_stack fix

From: Paul Mundt <lethal@linux-sh.org>
Date: Fri, 20 Oct 2006 15:30:55 +0900
Subject: sh: Convert INTC2 to IRQ table registration.

Currently the INTC2 code contains a fixed IRQ table that it
iterates through to set the handler type, we move this in to
the CPU subtype setup code instead and allow for submitting
the table that way.

This drops the ST40 tables, as nothing has been happening
with those processors, while converting the only existing
users to use the new table directly (SH7760 and SH7780).

Subject: [PATCH] separate bdi congestion functions from queue congestion
 functions

Separate out the concept of "queue congestion" from "backing-dev congestion".
Congestion is a backing-dev concept, not a queue concept.

The blk_* congestion functions are retained, as wrappers around the core
backing-dev congestion functions.

This proper layering is needed so that NFS can cleanly use the congestion
functions, and so that CONFIG_BLOCK=n actually links.

Subject: [PATCH] uml: reenable compilation of enable_timer, disabled by
 mistake

CONFIG_MODE_TT does not work there, the UML_ prefixed version must be used -
this causes a link-time failure when CONFIG_MODE_TT is enabled (i.e.  always
here, never by Jeff).

This should make sure that, for UML, host's configuration files are not
considered, which avoids various pains to the user.  Our dependency are such
that the obtained Kconfig will be valid and will lead to successful
compilation - however they cannot prevent an user from disabling any boot
device, and if an option is not set in the read .config (say
/boot/config-XXX), with make menuconfig ARCH=um, it is not set.  This always
disables UBD and all console I/O channels, which leads to non-working UML
kernels, so this bothers users - especially now, since it will happen on
almost every machine (/boot/config-`uname -r` exists almost on every machine).
 It can be workarounded with make defconfig ARCH=um, but it is non-obvious and
can be avoided, so please _do_ merge this patch.

Given the existence of options, it could be interesting to implement
(additionally) "option required" - with it, Kconfig will refuse reading a
.config file (from wherever it comes) if the given option is not set.  With
this, one could mark with it the option characteristic of the given
architecture (it was an old proposal of Roman Zippel, when I pointed out our
problem):

config UML
	option required
	default y

However this should be further discussed:
*) for x86, it must support constructs like:

==arch/i386/Kconfig==
config 64BIT
	option required
	default n
where Kconfig must require that CONFIG_64BIT is disabled or not present in the
read .config.

*) do we want to do such checks only for the starting defconfig or also for
   .config? Which leads to:
*) I may want to port a x86_64 .config to x86 and viceversa, or even among more
   different archs. Should that be allowed, and in which measure (the user may
   force skipping the check for a .config or it is only given a warning by
   default)?

Subject: [PATCH] uml: cleanup run_helper() API to fix a leak

Freeing the stack is left uselessly to the caller of run_helper in some cases
- this is taken from run_helper_thread, but here it is useless, so no caller
needs it and the only place where this happens has a potential leak - in case
of error neither run_helper() nor xterm_open() call free_stack().  At this
point passing a pointer is not needed - the stack pointer should be passed
directly, but this change is not done here.

Subject: [PATCH] uml: mmapper - remove just added but wrong "const" attribute

When enabling the mmapper driver I got warnings because this "const"
miscdevice structure is passed to function as non-const pointer; unlike struct
tty_operations, however, I verified that misc_{de,}register _do_ modify their
parameter, so this const attribute must be removed.

Since the purpose of the change was to guarantee that no lock was needed, add
a comment to prove this differently.

Subject: [PATCH] Fix potential interrupts during alternative patching

Interrupts must be disabled during alternative instruction patching.  On
systems with high timer IRQ rates, or when running in an emulator, timing
differences can result in random kernel panics because of running partially
patched instructions.  This doesn't yet fix NMIs, which requires extricating
the patch code from the late bug checking and is logically separate (and also
less likely to cause problems).

Subject: [PATCH] x86-64: x86_64 hot-add memory srat.c fix

  This patch corrects the logic used in srat.c to figure out what
parsing what action to take when registering hot-add areas.  Hot-add
areas should only be added to the node information for the
MEMORY_HOTPLUG_RESERVE case.  When booting MEMORY_HOTPLUG_SPARSE hot-add
areas on everything but the last node are getting include in the node
data and during kernel boot the pages are setup then the kernel dies
when the pages are used. This patch fixes this issue.

Subject: [PATCH] x86-64: Fix for arch/x86_64/pci/Makefile CFLAGS

The arch/x86_64/pci directory was giving problems in a wierd cross-compile
environment.  The exact cause is unknown, but the Makefile used CFLAGS
instead of EXTRA_CFLAGS.  From what I can tell from
Documentation/kbuild/makefiles.txt, CFLAGS should not be used for this, it
should be EXTRA_CFLAGS.  And it solves the cross-compile problem.

Subject: [PATCH] x86-64: fix page align in e820 allocator

Currently some code pieces assume that address returned by find_e820_area()
are page aligned.  But looks like find_e820_area() had no such intention
and hence one might end up stomping over some of the data.  One such case
is bootmem allocator initialization code stomped over bss.

This patch modified find_e820_area() to return page aligned address.  This
might be little wasteful of memory but at the same time probably it is
easier to handle page aligned memory.

Subject: [PATCH] x86: Use -maccumulate-outgoing-args

This avoids some problems with gcc 4.x and earlier generating
invalid unwind information. In 4.1 the option is default
when unwind information is enabled.

And it seems to generate smaller code too, so it's probably
a good thing on its own. With gcc 4.0:

i386:
4683198  902112  480868 6066178  5c9002 vmlinux (before)
4449895  902112  480868 5832875  5900ab vmlinux (after)

x86-64:
4939761 1449584  648216 7037561  6b6279 vmlinux (before)
4854193 1449584  648216 6951993  6a1439 vmlinux (after)

On 4.1 it shouldn't make much difference because it is
default when unwind is enabled anyways.

Subject: [PATCH] x86-64: Use irq_domain in ioapic_retrigger_irq

Thanks to YH Lu for spotting this.  It appears I missed this function when I
refactored allocate_irq_vector and introduced irq_domain, with the result that
all retriggered irqs would go to cpu 0 even if we were not prepared to receive
them there.

While reviewing YH's patch I also noticed that this function was missing
locking, and since I am now reading two values from two diffrent arrays that
looks like a race we might be able to hit in the real world.

Subject: [PATCH] x86-64: Put more than one cpu in TARGET_CPUS

TARGET_CPUS is the default irq routing poicy.  It specifies which cpus the
kernel should aim an irq at.  In physflat delivery mode we can route an irq to
a single cpu.  But that doesn't mean our default policy should only be a
single cpu is allowed.

By allowing the irq routing code to select from multiple cpus this enables
systems with more irqs then we can service on a single processor to actually
work.

I just audited and tested the code and irqbalance doesn't care, and the
io_apic.c doesn't care if we have extra cpus in the mask.  Everything will use
or assume we are using the lowest numbered cpu in the mask if we can't use
them all.

So this should result in no behavior changes except on systems that need it.

Thanks for YH Lu for spotting this problem in his testing.

Subject: [PATCH] x86-64: Overlapping program headers in physical addr space
 fix

o A recent change to vmlinux.ld.S file broke kexec as now resulting vmlinux
  program headers are overlapping in physical address space.

o Now all the vsyscall related sections are placed after data and after
  that mostly init data sections are placed. To avoid physical overlap
  among phdrs, there are three possible solutions.
	- Place vsyscall sections also in data phdrs instead of user
	- move vsyscal sections after init data in bss.
	- create another phdrs say data.init and move all the sections
	  after vsyscall into this new phdr.

o This patch implements the third solution.

Subject: [PATCH] x86-64: Revert timer routing behaviour back to 2.6.16 state

By default route the 8254 over the 8259 and only disable
it on ATI boards where this causes double timer interrupts.

This should unbreak some Nvidia boards where the timer doesn't
seem to tick of it isn't enabled in the 8259. At least one
VIA board also seemed to have a little trouble with the disabled
8259.

For 2.6.20 we'll try both dynamically without black listing, but I think
for .19 this is the safer approach because it has been already well tested
in earlier kernels. This also makes the x86-64 behaviour the same
as i386.

Command line options can change all this of course.

Subject: [MIPS] Fix aliasing bug in copy_to_user_page / copy_from_user_page

The current implementation uses a sequence of a cacheflush and a copy.
This is racy in case of a multithreaded debuggee and renders GDB
virtually unusable.

Aside this fixes a performance hog rendering access to /proc/cmdline very
slow and resulting in a enough cache stalls for the 34K AP/SP programming
model to make the bare metal code on the non-Linux VPE miss RT deadlines.

The main part of this patch was originally written by Ralf Baechle;
Atushi Nemoto did the the debugging.

Subject: [PATCH] x86-64: Fix C3 timer test

There was a typo in the C3 latency test to decide of the TSC
should be used or not. It used the C2 latency threshold, not the
C3 one. Fix that.

This should fix the time on various dual core laptops.

Subject: [PATCH] x86-64: increase PHB1 split transaction timeout

This patch increases the timeout for PCI split transactions on PHB1 on
the first Calgary to work around an issue with the aic94xx
adapter. Fixes kernel.org bugzilla #7180
(http://bugzilla.kernel.org/show_bug.cgi?id=7180)

Based on excellent debugging and a patch by Darrick J. Wong

Subject: [POWERPC] Add flatdevtree source

Add the latest version of the flatdevtree code and corresponding glue.

A phandle table now tracks values returned by ft_find_device().
The value returned by ft_find_device() is a phandle which is really
an index into the phandle table.  The phandle table contains the address
of the corresponding node.  When the flat dt is edited/moved, the node
pointers in the phandle table are updated accordingly so no phandles kept
by the caller become stale.

Subject: [POWERPC] Add non-OF serial console support

Add serial console support for non-OF systems.  There is a generic serial
console layer which calls a serial console driver.  Included is the serial
console driver for the ns16550 class of uarts.  Necessary support routines
are added as well.

Subject: [POWERPC] Simplify stolen time calculation

In calculating stolen time, we were trying to actually account for time
spent in the hypervisor.  We don't really have enough information to do
that accurately, so don't try.  Instead, we now calculate stolen time as
time that the current cpu thread is not actually dispatching instructions.
On chips without a PURR, we cannot do this, so stolen time will always
be zero.  On chips with a PURR, this is merely the difference between
the elapsed PURR values and the elapsed TB values.

This gives us much more sane vaules from tools such as mpstat, even if
they are still a bit strange e.g. 2 busy threads on one cpu will both
appear to have 50% user time and 50% stolen time while 1 busy thread on
a cpu will look like 100% user on one of them and 100% idle on the other.

Subject: [POWERPC] Fix up the OF functions to only do PCI stuff if PCI is
 actually configured

The original problem that inspired this patch was solved quite some time
ago (Turning off PCI didn't work), but this patch neatens things up a
little (I think), by putting all the PCI stuff inside a single CONFIG_PCI
block.  It also removes the OF PCI bus matching entries if CONFIG_PCI is
off.

Subject: [POWERPC] Move iSeries initrd logic into device tree

Remove the iSeries initrd logic, instead just store the initrd location and
size in the device tree so generic code can do the rest for us.

The iSeries code had a "feature" which the generic code lacks, ie. if the
compressed initrd is bigger than the configured ram disk size, we make
the ram disk size bigger. That's bogus, as the compressed size of the initrd
tells us nothing about how big the ram disk needs to be. If the ram disk
isn't big enough you just need to make CONFIG_BLK_DEV_RAM_SIZE larger.

Subject: [PATCH] x86-64: Simplify the vector allocator.

There is no reason to remember a per cpu position of which vector
to try.  Keeping a global position is simpler and more likely to
result in a global vector allocation even if I don't need or require
it.  For level triggered interrupts this means we are less likely to
acknowledge another cpus irq, and cause the level triggered irq to
harmlessly refire.

This simplification makes it easier to only access data structures
of  online cpus, by having fewer special cases to deal with.

Subject: [PATCH] x86-64: Only look at per_cpu data for online cpus.

When I generalized __assign_irq_vector I failed to pay attention
to what happens when you access a per cpu data structure for
a cpu that is not online.   It is an undefined case making any
code that does it have undefined behavior as well.

The code still needs to be able to allocate a vector across cpus
that are not online to properly handle combinations like lowest
priority interrupt delivery and cpu_hotplug.  Not that we can do
that today but the infrastructure shouldn't prevent it.

So this patch updates the places where we touch per cpu data
to only touch online cpus, it makes cpu vector allocation
an atomic operation with respect to cpu hotplug, and it updates
the cpu start code to properly initialize vector_irq so we
don't have inconsistencies.

Subject: [POWERPC] Fix hang in start_ldr if _end or _edata is unaligned

Quick fix for lack of memset(__bss_start, 0, _end-__bss_start) in
load_kernel().  If edata is unaligned, the loop will overwrite all
memory because r3 and r4 will never be equal.

Date: Tue, 24 Oct 2006 16:42:40 +1000
Subject: [POWERPC] Consolidate feature fixup code

There are currently two versions of the functions for applying the
feature fixups, one for CPU features and one for firmware features. In
addition, they are both in assembly and with separate implementations
for 32 and 64 bits. identify_cpu() is also implemented in assembly and
separately for 32 and 64 bits.

This patch replaces them with a pair of C functions. The call sites are
slightly moved on ppc64 as well to be called from C instead of from
assembly, though it's a very small change, and thus shouldn't cause any
problem.

Subject: [POWERPC] Support feature fixups in vdso's

This patch reworks the feature fixup mecanism so vdso's can be fixed up.
The main issue was that the construct:

        .long   label  (or .llong on 64 bits)

will not work in the case of a shared library like the vdso. It will
generate an empty placeholder in the fixup table along with a reloc,
which is not something we can deal with in the vdso.

The idea here (thanks Alan Modra !) is to instead use something like:

1:
        .long   label - 1b

That is, the feature fixup tables no longer contain addresses of bits of
code to patch, but offsets of such code from the fixup table entry
itself. That is properly resolved by ld when building the .so's. I've
modified the fixup mecanism generically to use that method for the rest
of the kernel as well.

Another trick is that the 32 bits vDSO included in the 64 bits kernel
need to have a table in the 64 bits format. However, gas does not
support 32 bits code with a statement of the form:

        .llong  label - 1b  (Or even just .llong label)

That is, it cannot emit the right fixup/relocation for the linker to use
to assign a 32 bits address to an .llong field. Thus, in the specific
case of the 32 bits vdso built as part of the 64 bits kernel, we are
using a modified macro that generates:

        .long   0xffffffff
        .llong  label - 1b

Note that is assumes that the value is negative which is enforced by
the .lds (those offsets are always negative as the .text is always
before the fixup table and gas doesn't support emiting the reloc the
other way around).

Subject: [POWERPC] Support feature fixups in modules

This patch adds support for feature fixups in modules. This involves
adding support for R_PPC64_REL64 relocs to the 64 bits module loader.
It also modifies modpost.c to ignore the powerpc fixup sections (or it
would warn when used in .init.text).

Subject: [POWERPC] Cell timebase bug workaround

The Cell CPU timebase has an erratum. When reading the entire 64 bits
of the timebase with one mftb instruction, there is a handful of cycles
window during which one might read a value with the low order 32 bits
already reset to 0x00000000 but the high order bits not yet incremeted
by one. This fixes it by reading the timebase again until the low order
32 bits is no longer 0. That might introduce occasional latencies if
hitting mftb just at the wrong time, but no more than 70ns on a cell
blade, and that was considered acceptable.

Subject: [POWERPC] spufs: fix another off-by-one bug in spufs_mbox_read

Currently, spufs_mbox_read transfers more bytes than requested on a
read.  If you ask for four bytes, you get eight.  This fixes it to
transfer the largest multiple of four bytes that is less than or equal
to the number you asked for.

Note: one nasty property of this file in spufs is that you can only
read multiples of four bytes in the first place, since there is no way
to atomically put back a few bytes into the hardware register.  Thus,
reading less than four bytes returns -EINVAL.  Asking for more than
four returns the largest possible multiple of four.

Subject: [POWERPC] IPIC: Fix spinlock recursion in set_irq_handler

This causes ipic_set_irq_type to set the handler directly rather
than call set_irq_handler, which causes spinlock recursion because
the lock is already held when ipic_set_irq_type is called.

I'm also not convinced that ipic_set_irq_type should be changing the
handler at all.  There seem to be several controllers that don't and
several that do.  Those that do would break what appears to be a common
usage of calling set_irq_chip_and_handler followed by set_irq_type, if a
non-standard handler were to be used.  OTOH, irq_create_of_mapping()
doesn't set the handler, but only calls set_irq_type().

This patch gets things working in the spinlock-debugging-enabled case,
but I'm curious as to where the handler setting is ideally supposed to be
done.  I don't see any documentation on set_irq_type() that clarifies
what the semantics are supposed to be.

Subject: [POWERPC] spufs: wrap mfc sdr access

SPRN_SDR1 and the SPE's MFC SDR are hypervisor resources and
are not accessible from a logical partition.  This change adds an
access wrapper.

When running on bare H/W, the spufs needs to only set the SPE's MFC SDR
to the value of the PPE's SPRN_SDR1 once at SPE initialization, so this
change renames mfc_sdr_set() to mfc_sdr_setup() and moves the
access of SPRN_SDR1 into the mmio wrapper.  It also removes the now
unneeded member mfc_sdr_RW from struct spu_priv1_collapsed.

Subject: [POWERPC] spufs: add support for nonschedulable contexts

This adds two new flags to spu_create:

SPU_CREATE_NONSCHED: create a context that is never moved
away from an SPE once it has started running. This flag
can only be used by tasks with the CAP_SYS_NICE capability.

SPU_CREATE_ISOLATED: create a nonschedulable context that
enters isolation mode upon first run. This requires the
SPU_CREATE_NONSCHED flag.

Subject: [POWERPC] spufs: allow isolated mode apps by starting the SPE loader

This patch adds general support for isolated mode SPE apps.

Isolated apps are started indirectly, by a dedicated loader "kernel".
This patch starts the loader when spe_create is invoked with the
ISOLATE flag. We do this at spe_create time to allow libspe to pass the
isolated app in before calling spe_run.

The loader is read from the device tree, at the location
"/spu-isolation/loader". If the loader is not present, an attempt to
start an isolated SPE binary will fail with -ENODEV.

Update: loader needs to be correctly aligned - copy to a kmalloced buf.
Update: remove workaround for systemsim/spurom 'L-bit' bug, which has
        been fixed.
Update: don't write to runcntl on spu_run_init: SPU is already running.
Update: do spu_setup_isolated earlier

Tested on systemsim.

Subject: [POWERPC] spufs: Add isolated-mode SPE recycling support

When in isolated mode, SPEs have access to an area of persistent
storage, which is per-SPE. In order for isolated-mode apps to
communicate arbitrary data through this storage, we need to ensure that
isolated physical SPEs can be reused for subsequent applications.

Add a file ("recycle") in a spethread dir to enable isolated-mode
recycling. By writing to this file, the kernel will reload the
isolated-mode loader kernel, allowing a new app to be run on the same
physical SPE.

This requires the spu_acquire_exclusive function to enforce exclusive
access to the SPE while the loader is initialised.

Subject: [POWERPC] cell: add shadow registers for pmd_reg

Many of the registers in the performance monitoring unit are write-only.
We need to save a "shadow" copy when we write to those registers so we
can retrieve the values if we need them later.

The new cbe_pmd_shadow_regs structure is added to the cbe_regs_map structure
so we have the appropriate per-node copies of these shadow values.

Subject: [POWERPC] cell: add support for registering sysfs attributes to spus

In order to add sysfs attributes to all spu's, there is a
need for a list of all available spu's. Adding the device_node
makes also sense, as it is needed for proper register access.
This patch also adds two functions to create and remove sysfs
attributes and attribute_groups to all spus.
That allows to group spu attributes in a subdirectory like:
/sys/devices/system/spu/spuX/group_name/what_ever
This will be used by cbe_thermal to group all attributes dealing with
thermal support in one directory.

Subject: [POWERPC] cell: add temperature to SPU and CPU sysfs entries

This patch adds a module that registers sysfs attributes to CPU and SPU
containing the temperature of the CBE.

They can be found under
/sys/devices/system/spu/cpuX/thermal/temperature[0|1]
/sys/devices/system/spu/spuX/thermal/temperature

The temperature is read from the on-chip temperature sensors.

Subject: [POWERPC] cell: use ppc_md->power_save instead of cbe_idle_loop

This moves the cell idle function to use the default cpu_idle
with a special power_save callback, like all other platforms
except iSeries already do.

It also makes it possible to disable this power_save function
with a new powerpc-specific boot option "powersave=off".

Subject: [POWERPC] add support for stopping spus from xmon

This patch adds support for stopping, and restarting, spus
from xmon. We use the spu master runcntl bit to stop execution,
this is apparently the "right" way to control spu execution and
spufs will be changed in the future to use this bit.

Testing has shown that to restart execution we have to turn the
master runcntl bit on and also rewrite the spu runcntl bit, even
if it is already set to 1 (running).

Stopping spus is triggered by the xmon command 'ss' - "spus stop"
perhaps. Restarting them is triggered via 'sr'. Restart doesn't
start execution on spus unless they were running prior to being
stopped by xmon.

Walking the spu->full_list in xmon after a panic, would mean
corruption of any spu struct would make all the others
inaccessible. To avoid this, and also to make the next patch
easier, we cache pointers to all spus during boot.

We attempt to catch and recover from errors while stopping and
restarting the spus, but as with most xmon functionality there are
no guarantees that performing these operations won't crash xmon
itself.

Subject: [POWERPC] add support for dumping spu info from xmon

This patch adds a command to xmon for dumping information about
spu structs. The command is 'sf' for "spu fields" perhaps, and
takes the spu number as an argument. This is the same value as the
spu->number field, or the "phys-id" value of a context when it is
bound to a physical spu.

We try to catch memory errors as we dump each field, hopefully this
will make the command reasonably robust, but YMMV. If people see a
need we can easily add more fields to the dump in future.

Output looks something like this:

Subject: [PATCH] uml: mconsole fixes

 * when we have stop/sysrq/go, we get pt_regs of whatever executes
   mc_work_proc().  Would be better to see what we had at the time of
   interrupt that got us stop.

 * stop/stop/stop.....  will give stack overflow.  Shouldn't allow stop
   from mconsole_stop().

 * stop/stop/go leaves us inside mconsole_stop() with
	os_set_fd_block(req->originating_fd, 0);
	reactivate_fd(req->originating_fd, MCONSOLE_IRQ);
   just done by nested mconsole_stop().  Ditto.

 * once we'd seen stop, there's a period when INTR commands are executed
   out of order (as they should; we might have the things stuck badly
   enough to never reach mconsole_stop(), but still not badly enough to
   block mconsole_interrupt(); in that situation we _want_ things like
   "cad" to be executed immediately).  Once we enter monsole_stop(), all
   INTR commands will be executed in order, mixed with PROC ones.  We'd
   better let user see that such change of behaviour has happened.
   (Suggested by lennert).

 * stack footprint of monsole_interrupt() is an atrocity; AFAICS we can
   safely make struct mc_request req; static in function there.

Subject: [PATCH] AVR32: Minor Makefile cleanup

Don't generate listing by default, remove unused LIBGCC variable and
rename generated disassembly and listing files to vmlinux.{s,lst}.

Also make sure that files generated during the build are actually
removed with make clean.

While ioremap() will happily map a physical address through the
P2 (uncached) segment when appropriate, iounmap() doesn't know how
to handle those mappings.

This patch makes iounmap() do the right thing, i.e. nothing, for
such mappings.

Subject: [PATCH] AVR32: Use __raw MMIO access for internal peripherals

The read[bwl] and write[bwl] functions are meant for accessing PCI
devices. How this is achieved on AVR32 is unknown, as there are no
systems with a PCI bridge available yet.

On-chip peripheral access, however, should not depend on how we end
up implementing PCI access, so using __raw_read[bwl]/__raw_write[bwl]
is the right thing to do for on-chip peripherals. This patch converts
the drivers for the static memory controller, interrupt controller,
PIO controller and system manager to use __raw MMIO access.

From 4130a4b206e7c628482aa12ec30949382c8cdc5e Mon Sep 17 00:00:00 2001
From: "David S. Miller" <davem@sunset.davemloft.net>
Date: Wed, 25 Oct 2006 22:31:06 -0700
Subject: [SPARC64]: Fix central/FHC bus handling on Ex000 systems.

1) probe_other_fhcs() wants to see only non-central FHC
   busses, so skip FHCs that don't sit off the root

2) Like SBUS, FHC can lack the appropriate address and
   size cell count properties, so add an of_busses[]
   entry and handlers for that.

3) Central FHC irq translator probing was buggy.  We
   were trying to use dp->child in irq_trans_init but
   that linkage is not setup at this point.

   So instead, pass in the parent of "dp" and look for
   the child "fhc" with parent "central".

Thanks to the tireless assistence of Ben Collins in tracking
down these problems and testing out these fixes.

Subject: [SPARC64]: Fix memory corruption in pci_4u_free_consistent().

The second argument to free_npages() was being incorrectly
calculated, which would thus access far past the end of the
arena->map[] bitmap.

sys_getcpu_wrapper wraps in to sys_tee, in what appears to be
a copy and paste error.  Switch it to point to sys_getcpu..

Subject: [PATCH] vmlinux.lds: consolidate initcall sections

Add a vmlinux.lds.h helper macro for defining the eight-level initcall table,
teach all the architectures to use it.

This is a prerequisite for a patch which performs initcall synchronisation for
multithreaded-probing.

Subject: [ARM] Fix SMP irqflags support

The IRQ changes a while back broke the build for SMP machines.
Fix up the SMP code to use set_irq_regs/get_irq_regs as
appropriate.  Also, fix a warning in arch/arm/kernel/time.c
where 'regs' becomes unused for SMP builds.

Add support for KBUILD_IMAGE on ARM.  This takes the usual target

(iow, without the arch/arm/boot prefix).

The second ethernet port on the Thecus n2100 was incorrectly assigned
to XINT1 instead of the correct XINT3 (PCI INTB instead of INTD), which
caused that port to be non-functional.

Subject: [PATCH] Fix "Remove the use of _syscallX macros in UML"

Fix commit 5f4c6bc1f369f20807a8e753c2308d1629478c61: it spits out warnings
about missing syscall prototype (it is in <unistd.h>) and it does not
recognize that two uses of _syscallX are to be resolved against kernel
headers in the source tree, not against _syscallX; they in fact do not
compile and would not work anyway.

If _syscallX macros will be removed from the kernel tree altogether, the
only reasonable solution for that piece of code is switching to open-coded
inline assembly (it's remapping the whole executable from memory, except
the page containing this code).

Subject: [PATCH] uml: fix compilation options for USER_OBJS

From: Jeff Dike <jdike@addtoit.com>, Paolo Giarrusso <blaisorblade@yahoo.it>

Make sure that when compiling USER_OBJS the correct compilation options are
passed; since they are compiled with USER_CFLAGS which is derived from
CFLAGS, make sure it is a recursively evaluated variable, so that changes
to CFLAGS done afterwards the inclusion of arch/$(ARCH)/Makefile are
reflected in USER_CFLAGS.

For instance, without this patch userspace objects are never compiled with
debug info active.

Subject: [MIPS] Ocelot G: Fix build error and numerous warnings.

The cause of the build errors was a 64-bit kernel being configured in
ocelot_g_defconfig without the code being 64-bit proof.  Fixed for now
by limiting 64-bit selection to SYS_SUPPORTS_64BIT_KERNEL if BROKEN.

Date: Sun, 29 Oct 2006 16:32:31 -0800
Subject: [SPARC64]: Fix Tomatillo/Schizo IRQ handling.

The code in schizo_irq_trans_init() should set irq_data->sync_reg
to the location of the SYNC register if this is Tomatillo, and set
it to zero otherwise.  But that is not what it is doing.

As a result, non-Tomatillo systems were trying to access a
non-existent register resulting in bus errors at the first
PCI interrupt.

Thanks to Roland Stigge for the bug report.

From bd71ab88deab3358241f22ed6c035c427aacc4e7 Mon Sep 17 00:00:00 2001
From: Jamie Lenehan <lenehan@twibble.org>
Date: Tue, 31 Oct 2006 12:35:02 +0900
Subject: sh: Fix IPR-IRQ's for IRQ-chip change breakage.

The conversion from IPR-IRQ to IRQ-chip resulted in the
ipr data being allocated in a local variable in
make_ipr_irq - breaking anything using IPR interrupts.

This changes all of the callers of make_ipr_irq to
allocate a static structure containing the IPR data which
is then passed to make_ipr_irq. This removes the need for
make_ipr_irq to allocate any additional space for the IPR
information.

Subject: [PATCH] uml ubd driver: allow using up to 16 UBD devices

With 256 minors and 16 minors used per each UBD device, we can allow the use
of up to 16 UBD devices per UML.

Also chnage parse_unit and leave to the caller (which already do it) the check
for excess numbers, since this is just supposed to do raw parsing.

Subject: [PATCH] uml ubd driver: document some struct fields

Add documentation about some fields in struct ubd, whose meaning is
non-obvious due to struct names (should change names altogether, I agree).

Subject: [PATCH] uml ubd driver: var renames

Rename the ubd_dev array to ubd_devs and then call any "struct ubd" ubd_dev
instead of dev, which doesn't make clear what we're treating (and no, it's not
hungarian notation - not any more than calling all vm_area_struct vma or all
inodes inode).

Subject: [PATCH] uml ubd driver: give better names to some functions.

To rethink locking, I needed to understand well what each function does.
While doing this I renamed some:

* ubd_close -> ubd_close_dev (since it pairs with ubd_open_dev)

* ubd_new_disk -> ubd_disk_register (it handles registration with the block
  layer - one hopes this makes clearer the difference with ubd_add())

Subject: [PATCH] uml ubd driver: change ubd_lock to be a mutex

This lock protects ubd setup and teardown, so is only used in process context;
beyond that, during such setup memory allocations must be performed and some
generic functions which can sleep must be called (such as add_disk()).  So the
only correct solution is to make it a mutex instead of a spin_lock.  No other
change is done - this lock must be acquired in different places but it's done
afterwards.

Subject: [PATCH] uml ubd driver: ubd_io_lock usage fixup

Add some comments about requirements for ubd_io_lock and expand its use.

When an irq signals that the "controller" (i.e.  another thread on the host,
which does the actual requests and is the only one blocked on I/O on the host)
has done some work, we call again the request function ourselves
(do_ubd_request).

We now do that with ubd_io_lock held - that's useful to protect against
concurrent calls to elv_next_request and so on.

XXX: Maybe we shouldn't call at all the request function.  Input needed on
this.  Are we supposed to plug and unplug the queue?  That code "indirectly"
does that by setting a flag, called do_ubd, which makes the request function
return (it's a residual of 2.4 block layer interface).

Meanwhile, however, merge this patch, which improves things.

Subject: [PATCH] uml ubd driver: convert do_ubd to a boolean variable

do_ubd is actually just a boolean variable - the way it is used currently is a
leftover from the old 2.4 block layer, but it is still used; its use is
suspicious, but removing it would be too intrusive for now and needs more
thinking.

Subject: [PATCH] uml ubd driver: do not store error codes as ->fd

To simplify error handling, make sure fd is saved into ubd_dev->fd only when
we are sure it is an fd and not an error code.

Subject: [PATCH] uml ubd driver: various little changes

Fix a small memory leak in ubd_config, and clearify the confusion which lead
to it.

Then, some little changes not affecting operations -
* move init functions together,
* add a comment about a potential problem in case of some evolution in the block layer,
* mark all initcalls as static __init functions
* mark an used once little function as inline
* document that mconsole methods are all called in process context (was
  triggered when checking ubd mconsole methods).

kallsyms now refers to addresses as '_text + 0xADDRESS', rather than just
'0xADDRESS', so we need to define _text.

Subject: [MIPS] Fixup migration to GENERIC_TIME

Since we already moved to GENERIC_TIME, we should implement alternatives
of old do_gettimeoffset routines to get sub-jiffies resolution from
gettimeofday().  This patch includes:

 * MIPS clocksource support (based on works by Manish Lachwani).
 * remove unused gettimeoffset routines and related codes.
 * remove unised 64bit do_div64_32().
 * simplify mips_hpt_init. (no argument needed, __init tag)
 * simplify c0_hpt_timer_init. (no need to write to c0_count)
 * remove some hpt_init routines.
 * mips_hpt_mask variable to specify bitmask of hpt value.
 * convert jmr3927_do_gettimeoffset to jmr3927_hpt_read.
 * convert ip27_do_gettimeoffset to ip27_hpt_read.
 * convert bcm1480_do_gettimeoffset to bcm1480_hpt_read.
 * simplify sb1250 hpt functions. (no need to subtract and shift)

Subject: [IA64] MCA recovery: Montecito support

The information in MCA records is filled in slightly differently on
Montecito than on Madison/McKinley.  Usually, the cache check and bus
check target identifiers have the same address.   On Montecito the
cache check and bus check target identifiers can be different if
a corrected error (ie SBE or unconsumed poison data) was encountered and
then an uncorrected error (ie DBE) was consumed.  In that case, the
cache check target identifier is the physical address of the DBE (that
caused the MCA to surface) while the bus check target identifier is the
physical address of the SBE.  This patch correctly finds the target
identifier that triggered the MCA.

If there are multiple valid cache target identifiers in the same
error record then use the one with the lowest cache level.

Subject: [IA64] move SAL_CACHE_FLUSH check later in boot

The check to see if the firmware drops interrupts during a
SAL_CACHE_FLUSH is done to early in the boot. SAL_CACHE_FLUSH expects
to be able to make PAL calls in virtual mode, on some cell based
machines a fault occurs causing a MCA. This patch moves the check
after mmu_context_init so the TLB and VHPT are properly setup.

Subject: [POWERPC] Fix various offb issues

This patch fixes a few issues in offb:

 - A test was inverted causing the palette hack to never work
(no device node was passed down to the init function)

 - Some cards seem to have their assigned-addresses property in a random
order, thus we need to try using of_get_pci_address() first, which will
fail if it's not a PCI device, and fallback to of_get_address() in that
case. of_get_pci_address() properly parsees assigned-addresses to test
the BAR number and thus will get it right whatever the order is.

 - Some cards (like GXT4500) provide a linebytes of 0xffffffff in the
device-tree which does no good. This patch handles that by using the
screen width when that happens. (Also fixes btext.c while at it).

 - Add detection of the GXT4500 in addition to the GXT2000 for the
palette hacks (we use the same hack, palette is linear in register space
at offset 0x6000).

Subject: [POWERPC] Fix oprofile support for e500 in arch/powerpc

Fixed a compile error in building the 85xx support with oprofile, and in
the process cleaned up some issues with the fsl_booke performance monitor
code.

* Reorganized FSL Book-E performance monitoring code so that the 7450
  wouldn't be built if the e500 was, and cleaned it up so it was more
  self-contained.

* Added a cpu_setup function for FSL Book-E.  The original
  cpu_setup function prototype had no arguments, assuming that
  the reg_setup function would copy the required information into
  variables which represented the registers.  This was silly for
  e500, since it has 1 register per counter (rather than 3 for
  all counters), so the code has been restructured to have
  cpu_setup take the current counter config array as an argument,
  with op_powerpc_setup() invoking op_powerpc_cpu_setup() through
  on_each_cpu(), and op_powerpc_cpu_setup() invoking the
  model-specific cpu_setup function with an argument.  The
  argument is ignored on all other platforms at present.

* Fixed a confusing line where a trinary operator only had two
  arguments

From 5d2efba64b231a1733c4048d1708d77e07f26426 Mon Sep 17 00:00:00 2001
From: Linas Vepstas <linas@austin.ibm.com>
Date: Mon, 30 Oct 2006 16:15:59 +1100
Subject: [POWERPC] Use 4kB iommu pages even on 64kB-page systems

The 10Gigabit ethernet device drivers appear to be able to chew
up all 256MB of TCE mappings on pSeries systems, as evidenced by
numerous error messages:

 iommu_alloc failed, tbl c0000000010d5c48 vaddr c0000000d875eff0 npages 1

Some experimentation indicates that this is essentially because
one 1500 byte ethernet MTU gets mapped as a 64K DMA region when
the large 64K pages are enabled. Thus, it doesn't take much to
exhaust all of the available DMA mappings for a high-speed card.

This patch changes the iommu allocator to work with its own
unique, distinct page size. Although the patch is long, its
actually quite simple: it just #defines a distinct IOMMU_PAGE_SIZE
and then uses this in all the places that matter.

As a side effect, it also dramatically improves network performance
on platforms with H-calls on iommu translation inserts/removes (since
we no longer call it 16 times for a 1500 bytes packet when the iommu HW
is still 4k).

In the future, we might want to make the IOMMU_PAGE_SIZE a variable
in the iommu_table instance, thus allowing support for different HW
page sizes in the iommu itself.

Changed qe_issue_cmd() to write cmd_input to the CECDR unmodified.  It
was treating cmd_input as a virtual address and tried to convert it to
a physical address.

Subject: [POWERPC] Make high hugepage areas preempt safe

Checking source for other get_paca()->field preemption dangers found that
open_high_hpage_areas does a structure copy into its paca while preemption
is enabled: unsafe however gcc accomplishes it.  Just remove that copy:
it's done safely afterwards by on_each_cpu, as in open_low_hpage_areas.

Subject: [POWERPC] Disallow kprobes on emulate_step and branch_taken

On powerpc, probing on emulate_step function will crash 2.6.18.1 when
it is triggered.

When kprobe is triggered, emulate_step() is on its kernel path and
will cause recursive kprobe fault.  And branch_taken() is called
in emulate_step().  This disallows kprobes on both of them.

Subject: [POWERPC] Make alignment exception always check exception table

The alignment exception used to only check the exception table for
-EFAULT, not for other errors. That opens an oops window if we can
coerce the kernel into getting an alignment exception for other reasons
in what would normally be a user-protected accessor, which can be done
via some of the futex ops. This fixes it by always checking the
exception tables.

Subject: i386: clean up io-apic accesses

This is preparation for fixing the ordering of the accesses that
got broken by the commit cf4c6a2f27f5db810b69dcb1da7f194489e8ff88 when
factoring out the "common" io apic routing entry accesses.

Move the accessor function (that were only used by io_apic.c) out
of a header file, and use proper memory-mapped accesses rather than
making up our own "volatile" pointers.

Subject: i386: write IO APIC irq routing entries in correct order

Since the "mask" bit is in the low word, when we write a new entry, we
need to write the high word first, before we potentially unmask it.

The exception is when we actually want to mask the interrupt, in which
case we want to write the low word first to make sure that the high word
doesn't change while the interrupt routing is still active.

Subject: [PATCH] powerpc: Eliminate "exceeds stub group size" linker warning

It turns out that the linker warnings on 64-bit powerpc about "section
blah exceeds stub group size" were being triggered by conditional
branches in head_64.S branching to global symbols, whether in
head_64.S or in other files.  This eliminates the warnings by making
some global symbols in head_64.S no longer global, and by rearranging
some branches.

Subject: [ARM] 3912/1: Make PXA270 advertise HWCAP_IWMMXT capability

ARM patch 3756/1 added HWCAP_IWMMXT.  This patch adds support
for broadcasting that info via /proc/cpuinfo and sets it for
the CPU features of the PXA270.

I've booted 19rc3 on a pxa270 and confirmed that the /proc/cpuinfo
shows "iwmmxt" in the Features.

Subject: [ARM] 3918/1: ixp4xx irq-chip rework

This is a rework of the ixp4xx irq_chip implementation.  The use of
two irq_chip structures and potentially switching between them is a
violation of the intended use of the IRQ framework.  The current
implementation does not work with current in-kernel spinlock debugging
or lockdep due to lock recursion problems caused by calling
set_irq_chip/handler from within the chip's set_irq_type().

This patch goes back to using one irq_chip structure and handling the
differences between edge/level, normal/GPIO interrupts inside the
ack/mask/unmask routines themselves.

From 73d15da44f34626b4ad18eb4d56e1c2c4aaed578 Mon Sep 17 00:00:00 2001

Subject: [ARM] 3921/1: S3C24XX: remove bast_defconfig

Remove the bast_defconfig, as it has not been updated
since 2.6.13. The s3c2410_defconfig should be a good
replacement.

Subject: [PATCH] uml: fix I/O hang

Fix a UML hang in which everything would just stop until some I/O happened
- a ping, someone whacking the keyboard - at which point everything would
start up again as though nothing had happened.

The cause was gcc reordering some code which absolutely needed to be
executed in the order in the source.  When unblock_signals switches signals
from off to on, it needs to see if any interrupts had happened in the
critical section.  The interrupt handlers check signals_enabled - if it is
zero, then the handler adds a bit to the "pending" bitmask and returns.
unblock_signals checks this mask to see if any signals need to be
delivered.

The crucial part is this:
	signals_enabled = 1;
	save_pending = pending;
	if(save_pending == 0)
		return;
	pending = 0;

In order to avoid an interrupt arriving between reading pending and setting
it to zero, in which case, the record of the interrupt would be erased,
signals are enabled.

What happened was that gcc reordered this so that 'save_pending = pending'
came before 'signals_enabled = 1', creating a one-instruction window within
which an interrupt could arrive, set its bit in pending, and have it be
immediately erased.

When the I/O workload is purely disk-based, the loss of a block device
interrupt stops the entire I/O system because the next block request will
wait for the current one to finish.  Thus the system hangs until something
else causes some I/O to arrive, such as a network packet or console input.

The fix to this particular problem is a memory barrier between enabling
signals and reading the pending signal mask.  An xchg would also probably
work.

Looking over this code for similar problems led me to do a few more
things:

- make signals_enabled and pending volatile so that they don't get cached
  in registers

- add an mb() to the return paths of block_signals and unblock_signals so
  that the modification of signals_enabled doesn't get shuffled into the
  caller in the event that these are inlined in the future.

Subject: [PATCH] uml: include tidying

In order to get the __NR_* constants, we need sys/syscall.h.
linux/unistd.h works as well since it includes syscall.h, however syscall.h
is more parsimonious.  We were inconsistent in this, and this patch adds
syscall.h includes where necessary and removes linux/unistd.h includes
where they are not needed.

asm/unistd.h also includes the __NR_* constants, but these are not the
glibc-sanctioned ones, so this also removes one such inclusion.

Subject: [SPARC]: Fix robust futex syscalls and wire up migrate_pages.

When I added the entries for the robust futex syscall entries, I
forgot to bump NR_SYSCALLS.  The current situation is error-prone
because NR_SYSCALLS lives in entry.S where the system call limit
checks are enforced.  Move the definition to asm/unistd.h in order to
make this mistake much more difficult to make.

And wire up sys_migrate_pages since the powerpc folks implemented the
compat wrapper for us.

Subject: AVR32: Get rid of board_early_init

board_early_init() is left over from some early prototyping work
where we had to initialize the SDRAM controller ourselves. This
depends on the kernel being loaded into static RAM, which just
isn't possible on any commercially available products today.

In order to run without a boot loader, we need to create a zImage
stub or have the debugger initialize the SDRAM for us (for really
low-level debugging)

Subject: AVR32: Fix thinko in generic_find_next_zero_le_bit()

The existing implementation of this function seems to be looking for
a one although it should be looking for a zero. This causes trouble
for the ext2 filesystem, which tends to report -ENOSPC without this
patch.

Fix this by complementing each word before scanning.

Subject: [S390] revert add_active_range() usage patch.

Commit 7676bef9c183fd573822cac9992927ef596d584c breaks DCSS support on
s390. DCSS needs initialized struct pages to work. With the usage of
add_active_range() only the struct pages for physically present pages
are initialized.
This could be fixed if the DCSS driver would initiliaze the struct pages
itself, but this doesn't work too. This is because the mem_map array
does not include holes after the last present memory area and therefore
there is nothing that could be initialized.
To fix this and to avoid some dirty hacks revert this patch for now.
Will be added later when we move to a virtual mem_map.

Subject: [S390] IRQs too early enabled.

setup_lowcore() calls ctl_set_bit() which returns withs interrupts
enabled. The setup arch code is not supposed to enable interrupts that
early. Therefore use the __ctl_set_bit() variant.
This fixes the not working lock dependency validator on non 64 bit
systems.

Subject: [MIPS] Ocelot C: Fix warning about missmatching format string.

  CC      arch/mips/momentum/ocelot_c/setup.o
arch/mips/momentum/ocelot_c/setup.c: In function 'momenco_time_init':
arch/mips/momentum/ocelot_c/setup.c:223: warning: format '%d' expects type 'int', but argument 2 has type 'long unsigned int'

Change data type to match format string; a 32-bit type better suits our
needs.

 o Fix warnings
 o 768MB worth of I/O ports were insane
 o 64-bit kernels don't need special handling because ioremap does the magic

Subject: [ARM] 3926/1: make timer led handle HZ != 100

The timer LED is unusable at HZ=large, since it's got
a hard-wired value of 100 ticks per cycle; when HZ=1024
(for example) it's essentially always-on.  This patch
just makes that be HZ ticks per cycle.

Date: Tue, 7 Nov 2006 03:19:15 +0100
Subject: [ARM] 3927/1: Allow show_mem() to work with holes in memory map.

show_mem() was not correctly handling holes in the memory
map.  It was treating the freed sections of the map as
though they contained valid struct page entries.  This
could cause incorrect debugging output or even a kernel
panic.

This patch keeps the struct meminfo around after system
initialization so that show_mem() can use it when
scanning memory.  show_mem() now walks over each bank
of each online node, rather than assuming that each node
contains a single contiguous bank.

This reverts commit de09bddb9d6f96785be470c832b881e6d72d589f.  It tried
to reserve the MMCONFIG mmio memory ranges, but since the MMCONFIG
information is broken and often bogus (which is why we don't dare use it
most of the time _anyway_), it does more harm than good.

Subject: x86-64: clean up io-apic accesses

This is just commit 130fe05dbc0114609cfef9815c0c5580b42decfa ported to
x86-64, for all the same reasons.  It cleans up the IO-APIC accesses in
order to then fix the ordering issues.

We move the accessor functions (that were only used by io_apic.c) out of
a header file, and use proper memory-mapped accesses rather than making
up our own "volatile" pointers.

Subject: x86-64: write IO APIC irq routing entries in correct order

This is the x86-64 version of f9dadfa71bc594df09044da61d1c72701121d802
that did the same thing on i386.

Since the "mask" bit is in the low word, when we write a new entry, we
need to write the high word first, before we potentially unmask it.

The exception is when we actually want to mask the interrupt, in which
case we want to write the low word first to make sure that the high word
doesn't change while the interrupt routing is still active.

Subject: [PATCH] Regression in 2.6.19-rc microcode driver

If the microcode driver is built in (rather than module) there are some,
ehm, interesting effects happening due to the new "call out to userspace"
behavior that is introduced..  and which runs too early.  The result is a
boot hang; which is really nasty.

The patch below is a minimally safe patch to fix this regression for 2.6.19
by just not requesting actual microcode updates during early boot.  (That
is a good idea in general anyway)

The "real" fix is a lot more complex given the entire cpu hotplug scenario
(during cpu hotplug you normally need to load the microcode as well); but
the interactions for that are just really messy at this point; this fix at
least makes it work and avoids a full detangle of hotplug.

There are two bugs in the kretprobe-booster.

1) It doesn't make room for gs registers.

2) It doesn't change status of the current kprobe.  This status will
   effect the fault handling.

This patch fixes these bugs and, additionally, saves skipped registers for
compatibility with the original kretprobe.

When ACPI && NUMA, pxm_to_node is used and it exists in drivers/acpi/numa.c

Tony said:

  The patch makes sense ...  if you pick both of "ACPI" and "NUMA", then you
  need (and should automatically be given) ACPI_NUMA too.

  The only open question is whether there is a better way of getting there.
  Perhaps with less configuration options in the first place?  We are heading
  towards a future where so many systems will be NUMA that there would seem to
  be little benefit in keeping ACPI_NUMA separate from ACPI ...  but perhaps
  we aren't quite there yet.

Subject: [PATCH] htirq: refactor so we only have one function that writes to
 the chip

This refactoring actually optimizes the code a little by caching the value
that we think the device is programmed with instead of reading it back from
the hardware.  Which simplifies the code a little and should speed things up a
bit.

This patch introduces the concept of a ht_irq_msg and modifies the
architecture read/write routines to update this code.

There is a minor consistency fix here as well as x86_64 forgot to initialize
the htirq as masked.

Subject: [POWERPC] Make sure initrd and dtb sections get into zImage correctly

The "wrapper" script was using the wrong names for the initrd and
dtb (device-tree blob) sections.  This fixes it, and also ensures
the symbols for the start and end of the dtb get defined correctly.

Subject: [POWERPC] pseries: Force 4k update_flash block and list sizes

The enablement of 64k pages on pseries platforms exposed a bug in
the RTAS mechanism for updating firmware.  RTAS assumes 4k for flash
block and list sizes, and use of any other sizes results in a failure,
even though PAPR does not specify any such requirement.

This patch changes the rtas_flash module to force the use of 4k memory
block and list sizes when preparing and sending a firmware image to
RTAS.  The rtas_flash function now uses a slab cache of 4k blocks with
4k alignment, rather than get_zeroed_page(), to allocate the memory for
the flash blocks and lists.  The 4k alignment requirement is specified
in PAPR.

This fixes a typo in the "new style" code for mapping SPE resources,
which causes it to try to map the same resource 4 times.

It also adds some pr_debug's that are useful to track down issues with
the firmware when bringinh up new machines.

Subject: [ARM] Remove PM_LEGACY=y from selected ARM defconfigs

Most ARM defconfigs don't actually need to have PM_LEGACY enabled.
Disable it for ATEB9200, Collie, IXP4xx, OMAP H2, S3C2410 and
Versatile.

Since iSeries is merged to MULTIPLATFORM, there is no way to build a 64bit

dev_t boot_dev is declared in arch/powerpc/kernel/setup_32.c

It is only used in arch/powerpc/platforms/powermac/setup.c, so make
it static in this file.

From a9b14973a8c42b2aecc968851372203c6567e196 Mon Sep 17 00:00:00 2001

Date: Thu, 19 Oct 2006 19:52:26 -0500
Subject: [PATCH] Slight refactor of interrupt mapping for FSL parts

* Cleaned up interrupt mapping a little by adding a helper
  function which parses the irq out of the device-tree, and puts
  it into a resource.
* Changed the arch/ppc platform files to specify PHY_POLL, instead of -1
* Changed the fixed phy to use PHY_IGNORE_INTERRUPT
* Added ethtool.h and mii.h to phy.h includes

Subject: [PATCH] Do a single one-line printk in bad_page_fault()

bad_page_fault() prints a message telling the user what type of bad
fault we took. The first line of this message is currently implemented
as two separate printks. This has the unfortunate effect that if
several cpus simultaneously take a bad fault, the first and second parts
of the printk get jumbled up, which looks dodge and is hard to read.

So do a single one-line printk for each fault type.

Fix MSPEC driver to build for non SN2 enabled configs as the driver should
work in cached and uncached modes (no fetchop) on these systems.  In
addition make MSPEC select IA64_UNCACHED_ALLOCATOR, which is required for
it and move it to arch/ia64/Kconfig to avoid warnings on non ia64
architectures running allmodconfig.  Once the Kconfig code is fixed, we can
move it back.

Subject: [PATCH] x86-64: shorten the x86_64 boot setup GDT to what the comment
 says

Stephen Tweedie, Herbert Xu, and myself have been struggling with a very
nasty bug in Xen.  But it also pointed out a small bug in the x86_64
kernel boot setup.

The GDT limit being setup by the initial bzImage code when entering into
protected mode is way too big.  The comment by the code states that the
size of the GDT is 2048, but the actual size being set up is much bigger
(32768). This happens simply because of one extra '0'.

Instead of setting up a 0x800 size, 0x8000 is set up.  On bare metal this
is fine because the CPU wont load any segments unless  they are
explicitly used.  But unfortunately, this breaks Xen on vmx FV, since it
(for now) blindly loads all the segments into the VMCS if they are less
than the gdt limit. Since the real mode segments are around 0x3000, we are
getting junk into the VMCS and that later causes an exception.

Stephen Tweedie has written up a patch to fix the Xen side and will be
submitting that to those folks. But that doesn't excuse the GDT limit
being a magnitude too big.

AK: changed to compute true gdt size in assembler, fixed comment

x86_64: setup saved_max_pfn correctly

2.6.19-rc4 has broken CONFIG_CRASH_DUMP support on x86_64. It is impossible
to read out the kernel contents from /proc/vmcore because saved_max_pfn is set
to zero instead of the max_pfn value before the user map is setup.

This happens because saved_max_pfn is initialized at parse_early_param() time,
and at this time no active regions have been registered. save_max_pfn is setup
from e820_end_of_ram(), more exact find_max_pfn_with_active_regions() which
returns 0 because no regions exist.

This patch fixes this by registering before and removing after the call
to e820_end_of_ram().

Subject: [PATCH] x86: Add acpi_user_timer_override option for Asus boards

Timer overrides are normally disabled on Nvidia board because
they are commonly wrong, except on new ones with HPET support.
Unfortunately there are quite some Asus boards around that
don't have HPET, but need a timer override.

We don't know yet how to handle this transparently,
but at least add a command line option to force the timer override
and let them boot.

Subject: [PATCH] x86-64: Fix vgetcpu when CONFIG_HOTPLUG_CPU is disabled

The vgetcpu per CPU initialization previously relied on CPU hotplug
events for all CPUs to initialize the per CPU state. That only
worked only on kernels with CONFIG_HOTPLUG_CPU enabled.  On the
others some CPUs didn't get their state initialized properly
and vgetcpu wouldn't work.

Change the initialization sequence to instead run in a normal
initcall (which runs after the normal CPU bootup) and initialize
all running CPUs there. Later hotplug CPUs are still handled
with an hotplug notifier.

This actually simplifies the code somewhat.

Subject: [PATCH] hugetlb: prepare_hugepage_range check offset too

(David:)

If hugetlbfs_file_mmap() returns a failure to do_mmap_pgoff() - for example,
because the given file offset is not hugepage aligned - then do_mmap_pgoff
will go to the unmap_and_free_vma backout path.

But at this stage the vma hasn't been marked as hugepage, and the backout path
will call unmap_region() on it.  That will eventually call down to the
non-hugepage version of unmap_page_range().  On ppc64, at least, that will
cause serious problems if there are any existing hugepage pagetable entries in
the vicinity - for example if there are any other hugepage mappings under the
same PUD.  unmap_page_range() will trigger a bad_pud() on the hugepage pud
entries.  I suspect this will also cause bad problems on ia64, though I don't
have a machine to test it on.

(Hugh:)

prepare_hugepage_range() should check file offset alignment when it checks
virtual address and length, to stop MAP_FIXED with a bad huge offset from
unmapping before it fails further down.  PowerPC should apply the same
prepare_hugepage_range alignment checks as ia64 and all the others do.

Then none of the alignment checks in hugetlbfs_file_mmap are required (nor
is the check for too small a mapping); but even so, move up setting of
VM_HUGETLB and add a comment to warn of what David Gibson discovered - if
hugetlbfs_file_mmap fails before setting it, do_mmap_pgoff's unmap_region
when unwinding from error will go the non-huge way, which may cause bad
behaviour on architectures (powerpc and ia64) which segregate their huge
mappings into a separate region of the address space.

Subject: [PATCH] Use delayed disable mode of ioapic edge triggered interrupts

Komuro reports that ISA interrupts do not work after a disable_irq(),
causing some PCMCIA drivers to not work, with messages like

	eth0: Asix AX88190: io 0x300, irq 3, hw_addr xx:xx:xx:xx:xx:xx
	eth0: found link beat
	eth0: autonegotiation complete: 100baseT-FD selected
	eth0: interrupt(s) dropped!
	eth0: interrupt(s) dropped!
	eth0: interrupt(s) dropped!
	...

Linus Torvalds <torvalds@osdl.org> said:

  "Now, edge-triggered interrupts are a _lot_ harder to mask, because the
   Intel APIC is an unbelievable piece of sh*t, and has the edge-detect logic
   _before_ the mask logic, so if a edge happens _while_ the device is
   masked, you'll never ever see the edge ever again (unmasking will not
   cause a new edge, so you simply lost the interrupt).

   So when you "mask" an edge-triggered IRQ, you can't really mask it at all,
   because if you did that, you'd lose it forever if the IRQ comes in while
   you masked it. Instead, we're supposed to leave it active, and set a flag,
   and IF the IRQ comes in, we just remember it, and mask it at that point
   instead, and then on unmasking, we have to replay it by sending a
   self-IPI."

This trivial patch solves the problem.

Subject: [IA64] bte_unaligned_copy() transfers one extra cache line.

When called to do a transfer that has a start offset within the cache
line which is uneven between source and destination and a length which
terminates the source of the copy exactly on a cache line, one extra
line gets copied into a temporary buffer.  This is normally not an issue
since the buffer is a kernel buffer and only the requested information
gets copied into the user buffer.

The problem arises when the source ends at the very last physical page
of memory.  That last cache line does not exist and results in the SHUB
chip raising an MCA.

this is because the gcc-x86_64-has-stack-protector.sh script

this crash happened because it did not sanitize the dwarf2 data it
got, and got an unaligned stack pointer - which happily walked past
the process stack (and eventually reached the end of kernel memory
and pagefaulted there) due to this naive iteration condition:

        HANDLE_STACK (((long) stack & (THREAD_SIZE-1)) != 0);

note that i386 is alot more conservative when it comes to trusting
stack pointers:

  static inline int valid_stack_ptr(struct thread_info *tinfo, void *p)
  {
         return  p > (void *)tinfo &&
                 p < (void *)tinfo + THREAD_SIZE - 3;
  }

but the x86_64 code did not take this bit of i386 code.

The fix is to align the stack pointer.

The scheduler on Andreas Friedrich's hyperthreading system stopped
working properly: the scheduler would never move tasks to another CPU!
The lask known working kernel was 2.6.8.

After a couple of attempts to corner the bug, the following smoking gun
was found:

a quick look at cpu_idle_wait() shows how broken that code is
on i386: it changes the init task's affinity map but never
restores it ...

and because all userspace tasks get forked by init, they all
inherited that single-CPU affinity mask. x86_64 cloned this
bug too.

Subject: x86: be more careful when walking back the frame pointer chain

When showing the stack backtrace, make sure that we never accept not
only an unchanging frame pointer, but also a frame pointer that moves
back down the stack frame.  It must always grow up (toward older stack
frames).

I doubt this has triggered, but a subtly corrupt stack with extremely
unlucky contents could cause us to loop forever on a bogus endless frame
pointer chain.

This review was triggered by much worse problems happening in some of
the other stack unwinding code.

ARM doesn't source drivers/Kconfig like most architectures do, so the
newly added drivers/ata is currently not made available on ARM.  SATA
is used on some ARM machines, like the Thecus N2100, so we need to
source drivers/ata/Kconfig.

Subject: [POWERPC] Fix ucc_geth of_device discovery on mpc832x

mpc832x, as in mpc8360, needs to explicitly find and create the
platform device for ucc_geth in 2.6.19.  This code will likely be
readapted to Benh's new of_ methods for 2.6.20.

Subject: WorkStruct: Separate delayable and non-delayable events.

Separate delayable work items from non-delayable work items be splitting them
into a separate structure (delayed_work), which incorporates a work_struct and
the timer_list removed from work_struct.

The work_struct struct is huge, and this limits it's usefulness.  On a 64-bit
architecture it's nearly 100 bytes in size.  This reduces that by half for the
non-delayable type of event.

Subject: WorkStruct: Pass the work_struct pointer instead of context data

Pass the work_struct pointer to the work function rather than context data.
The work function can use container_of() to work out the data.

For the cases where the container of the work_struct may go away the moment the
pending bit is cleared, it is made possible to defer the release of the
structure by deferring the clearing of the pending bit.

To make this work, an extra flag is introduced into the management side of the
work_struct.  This governs auto-release of the structure upon execution.

Ordinarily, the work queue executor would release the work_struct for further
scheduling or deallocation by clearing the pending bit prior to jumping to the
work function.  This means that, unless the driver makes some guarantee itself
that the work_struct won't go away, the work function may not access anything
else in the work_struct or its container lest they be deallocated..  This is a
problem if the auxiliary data is taken away (as done by the last patch).

However, if the pending bit is *not* cleared before jumping to the work
function, then the work function *may* access the work_struct and its container
with no problems.  But then the work function must itself release the
work_struct by calling work_release().

In most cases, automatic release is fine, so this is the default.  Special
initiators exist for the non-auto-release case (ending in _NAR).

Subject: [PATCH] uml: make execvp safe for our usage

Reimplement execvp for our purposes - after we call fork() it is fundamentally
unsafe to use the kernel allocator - current is not valid there.  So we simply
pass to our modified execvp() a preallocated buffer.  This fixes a real bug
and works very well in testing (I've seen indirectly warning messages from the
forked thread - they went on the pipe connected to its stdout and where read
as a number by UML, when calling read_output().  I verified the obtained
number corresponded to "BUG:").

The added use of __cant_sleep() is not a new bug since __cant_sleep() is
already used in the same function - passing an atomicity parameter would be
better but it would require huge change, stating that this function must not
be called in atomic context and can sleep is a better idea (will make sure of
this gradually).

Subject: [ARM] Add PM_LEGACY defaults

Eliminate two warnings:

kernel/power/pm.c:205: warning: 'pm_register' is deprecated (declared at kernel/power/pm.c:64)
kernel/power/pm.c:206: warning: 'pm_send_all' is deprecated (declared at kernel/power/pm.c:180)

by updating defconfig files to contain a sensible PM_LEGACY default.

Commit 2c8c0e6b8d7700a990da8d24eff767f9ca223b96 ("[PATCH] Convert x86-64
to early param") broke the earlyprintk=...,keep feature.

This restores that functionality.  Tested on x86_64.  Must-have for
v2.6.19, no risk.

Previously it would check for alignment only, which could break
if the stack pointer was unaligned. Now explicitely check if the
stack pointer is in the stack page of the current process.

Ported from i386.

Subject: [MIPS] page.h: remove __pa() usages.

__pa() was used by virt_to_page() and virt_addr_valid(). These
latter are used when kernel is initialised so __pa() is not
appropriate, we use virt_to_phys() instead.

Futhermore __pa() is going to take care of CKSEG0/XKPHYS
address mix for 64 bit kernels. This makes __pa() more complex
than virt_to_phys() and this extra work is not needed by
virt_to_page() and virt_addr_valid().

Eventually it consolidates virt_to_phys() prototype by making
its argument 'const'. this avoids some warnings that was due
to some virt_to_page() usages which pass const pointer.

Subject: [MIPS] setup.c: get ride of CPHYSADDR()

and use new __pa() implementation instead introduced by the previous
patch. Indeed this macro can be used now even by the 64 bit kernels
with CONFIG_BUILD_ELF64=n config.

Subject: [MIPS] Make free_init_pages() arguments to be physical addresses

It allows caller of this function to not care about CKSEG0/XKPHYS
address mixes. It's now automatically done by free_init_pages().

We can now safely remove hack needed by 64 bit kernels with
CONFIG_BUILD_ELF64=n in free_initmem().

Subject: [MIPS] Load modules to CKSEG0 if CONFIG_BUILD_ELF64=n

This is a patch to load 64-bit modules to CKSEG0 so that can be
compiled with -msym32 option.  This makes each module ~10% smaller.

* introduce MODULE_START and MODULE_END
* custom module_alloc()
* PGD for modules
* change XTLB refill handler synthesizer
* enable -msym32 for modules again
  (revert ca78b1a5c6a6e70e052d3ea253828e49b5d07c8a)

New XTLB refill handler looks like this:

+ 	help
+ 	  kexec is a system call that implements the ability to shutdown your
+ 	  current kernel, and to start another kernel.  It is like a reboot
+ 	  but it is indepedent of the system firmware.   And like a reboot
+ 	  you can start any kernel with it, not just Linux.
+
+ 	  The name comes from the similiarity to the exec system call.
+
+ 	  It is an ongoing process to be certain the hardware in a machine
+ 	  is properly shutdown, so do not be surprised if this code does not
+ 	  initially work for you.  It may help to enable device hotplugging
+ 	  support.  As of this writing the exact hardware interface is
+ 	  strongly in flux, so no good recommendation can be made.

Subject: [MIPS] IRQ cleanups

This is a big irq cleanup patch.

* Use set_irq_chip() to register irq_chip.
* Initialize .mask, .unmask, .mask_ack field.  Functions for these
  method are already exist in most case.
* Do not initialize .startup, .shutdown, .enable, .disable fields if
  default routines provided by irq_chip_set_defaults() were suitable.
* Remove redundant irq_desc initializations.
* Remove unnecessary local_irq_save/local_irq_restore, spin_lock.

With this cleanup, it would be easy to switch to slightly lightwait
irq flow handlers (handle_level_irq(), etc.) instead of __do_IRQ().

Though whole this patch is quite large, changes in each irq_chip are
not quite simple.  Please review and test on your platform.  Thanks.

From: Atsushi Nemoto <anemo@mba.ocn.ne.jp>

Subject: [MIPS] use generic_handle_irq, handle_level_irq, handle_percpu_irq

Further incorporation of generic irq framework.  Replacing __do_IRQ()
by proper flow handler would make the irq handling path a bit simpler
and faster.

* use generic_handle_irq() instead of __do_IRQ().
* use handle_level_irq for obvious level-type irq chips.
* use handle_percpu_irq for irqs marked as IRQ_PER_CPU.
* setup .eoi routine for irq chips possibly used with handle_percpu_irq.

Subject: [MIPS] Remove redundant r4k_blast_icache() calls

r4k_flush_cache_all() and r4k_flush_cache_mm() case: these are noop if
the CPU did not have dc_aliases.  It would mean we do not need to care
about icache here.

r4k_flush_cache_range case: if r4k_flush_cache_mm() did not need to
care about icache, it would be same for this function.

Subject: [MIPS] do_IRQ cleanup

Now we have both function and macro version of do_IRQ() and the former
is used only by DEC and non-preemptive kernel.  This patch makes
everyone use the macro version and removes the function version.

Subject: [ARM] Improve reliability of APM-emulation suspend

The APM emulation can sometimes cause suspend to fail to work due
to apparantly waiting for some process to acknowledge an event when
it actually has already done so.  We re-jig the event handling to
work around this behaviour.

Subject: [ARM] Remove DEBUG_WAITQ

DEBUG_WAITQ appears to have been removed by others, but no one
removed the configuration option from ARM.  Remote it from both
Kconfig.debug and all default configurations.

Subject: [ARM] 3939/1: don't reset SA11x0 clock counter

Don't reset OSCR to zero as this prevents us from having a contiguous
time source. The value returned by sched_clock() is reset to zero in the
middle of the boot process otherwise, making CONFIG_PRINTK_TIME rather
messed up.

Subject: [ARM] 3911/2: Simplify alloc_thread_info on ARM

Remove ARM local cache of 4 struct thread_info.
Can cause oops under certain circumstances.

Russell indicated the original optimization was
required on older kernels to avoid thread starvation
on memory fragmentation, but may no longer be
required.  I've updated the patch to 19rc4 and
ensured no <config.h> dain-bramage slipped in this
time (sorry about that).

Original description follows:

I was given some test results which pointed to an
Oops in alloc_thread_info (happened 2x), and after
looking at the code, I see that ARM has its own
local cache of 4 struct thread_info. There wasn't
any clear (to me) synchronization between the
alloc_thread_info and the free_thread_info.

I looked over the other arch, and they all simply
allocate them on an as needed basis, so I simplified
the ARM to do the same, based on the other arch
(e.g. PPC) and the folks doing the testing have
indicated that this fixed the oops.

Subject: [ARM] Fix Versatile PB initialisation to use .init_machine

There's no point having the Versatile PB initialisation using an
arch_initcall() and then checking whether it's running on a
Versatile PB board - this is what the .init_machine function
pointer in the machine description is for.  Use it.

Subject: [ARM] 3946/1: AT91: at91_arch_reset and at91_extern_irq

The external interrupt sources are different on the various AT91
processors.  This patch introduces the global 'at91_extern_irq' variable
that contains a bitset of the available external interrupt sources.

The processor reset mechanism also differs on the various AT91
processors.  This patch also adds a global 'at91_arch_reset' callback
(from system.h) into the processor-specific code to perform the reset.

From 55d8baee4a0b4709061104f7a56f53a310de76ac Mon Sep 17 00:00:00 2001
From: Andrew Victor <andrew@sanpeople.com>
Date: Thu, 30 Nov 2006 17:16:43 +0100
Subject: [ARM] 3954/1: AT91: Update drivers for new headers

This patch updates the drivers (and other files) which include the
hardware headers.  This fixes the breakage introduced in patches 3950/1
and 3951/1 (those patches were getting big).

The AVR32 architecture uses the same serial driver and had its own copy
of at91rm9200_pdc.h.  Renamed it to at91_pdc.h

Subject: [ARM] 3957/1: AT91: Physically mapped flash on DK and EK boards

This patch converts the old CONFIG_MTD_PHYSMAP_ options to the new
physmap API by creating a physmap platform device for the NOR flash
found on the Atmel AT91RM9200-DK and AT91RM9200-EK boards.

Subject: [ARM] 3960/1: AT91: Final SAM9 intergration patches.

This patch includes a number of small changes for integrating the
AT91SAM9261 and AT91SAM0260 support.

      * Can only select support for one AT91 processor at a time.
      * Remove most of the remaining static memory mapping for the
        AT91RM9200.
      * Reserve 1Mb of memory below the IO for mapping the internal SRAM
        and any custom board-specific devices (ie, FPGA).
      * The SAM9260 has more serial ports, so increase the maximum to 7.
      * Define the standard chipselect addresses, and define other
        addresses relative to those.
      * CLOCK_TICK_RATE is different on the SAM926x's.

Subject: [ARM] 3965/1: ixp2000: fix handling of pci master aborts

The master abort check in ixp2000_pci_read_config() recently started
failing due to the compiler optimising out the read access following
the clearing of pci_master_aborts.  Mark pci_master_aborts volatile to
force the compiler to reload it on every use.

Subject: [ARM] 3963/1: AT91: Update configuration files

A number of configuration file changes.

These are mainly to replace references to ARCH_AT91RM9200 and
ARCH_AT91SAM9261 with the common/generic ARCH_AT91.  That way we don't
need to mention every specific AT91 processor explicitly.

Also adds the configuration option for AT91SAM9260-EK and AT91SAM9261-EK
boards.

Subject: [ARM] 3966/1: AT91: RM9200 device data update

This patch contains various updates the at91rm9200_devices.c file:
      * Consistent naming of resources and platform_devices.
      * PCMCIA/Compact Flash: Configuration of the memory controller
        moved out of the driver and into this file.
      * MMC: Enable the VCC pin (if one is configured)
      * MMC: Enable the internal pullups on the I/O pins.
      * NAND: Configuration of the memory controller moved out of the
        driver and into this file.
      * Added TWI/I2C resources.
      * The names of some of the CONFIG_ variables were changed.

Subject: [ARM] 3958/1: add platform device (pxa2xx-udc)to ixp4xx

Create include/asm-arm/arch-ixp4xx/udc.h and
add platfrom device ixp4xx_udc_device into
arch/arm/mach-ixp4xx/common.c.

This allows us to use pxa2xx-udc on
the ixp4xx platfrom. Both pxa2xx and
ixp4xx use the same device controller.

Subject: PCI: quirks: fix the festering mess that claims to handle IDE quirks

The number of permutations of crap we do is amazing and almost all of it
has the wrong effect in 2.6.

At the heart of this is the PCI SFF magic which says that compatibility
mode PCI IDE controllers use ISA IRQ routing and hard coded addresses
not the BAR values. The old quirks variously clears them, sets them,
adjusts them and then IDE ignores the result.

In order to drive all this garbage out and to do it portably we need to
handle the SFF rules directly and properly. Because we know the device
BAR 0-3 are not used in compatibility mode we load them with the values
that are implied (and indeed which many controllers actually
thoughtfully put there in this mode anyway).

This removes special cases in the IDE layer and libata which now knows
that bar 0/1/2/3 always contain the correct address. It means our
resource allocation map is accurate from boot, not "mostly accurate"
after ide is loaded, and it shoots lots of code. There is also lots more
code and magic constant knowledge to shoot once this is in and settled.

Been in my test tree for a while both with drivers/ide and with libata.
Wants some -mm shakedown in case I've missed something dumb or there are
corner cases lurking.

Subject: PCI: Use pci_generic_prep_mwi on ia64

The pci_generic_prep_mwi() code does everything that pcibios_prep_mwi()
does on ia64.  All we need to do is be sure that pci_cache_line_size
is set appropriately, and we can delete pcibios_prep_mwi().

Using SMP_CACHE_BYTES as the default was wrong on uniprocessor machines
as it is only 8 bytes.  The default in the generic code of L1_CACHE_BYTES
is at least as good.

Subject: PCI: Use pci_generic_prep_mwi on sparc64

The setting of the CACHE_LINE_SIZE register in sparc64's pci
initialisation code isn't quite adequate as the device may have
incompatible requirements.  The generic code tests for this, so switch
sparc64 over to using it.

Since sparc64 has different L1 cache line size and PCI cache line size,
it would need to override the generic code like i386 and ia64 do.  We
know what the cache line size is at compile time though, so introduce a
new optional constant PCI_CACHE_LINE_BYTES.

Subject: Altix: Add initial ACPI IO support

First phase in introducing ACPI support to SN.
In this phase, when running with an ACPI capable PROM,
the DSDT will define the root busses and all SN nodes
(SGIHUB, SGITIO). An ACPI bus driver will be registered
for the node devices, with the acpi_pci_root_driver being
used for the root busses. An ACPI vendor descriptor is
now used to pass platform specific information for both
nodes and busses, eliminating the need for the current
SAL calls. Also, with ACPI support, SN fixup code is no longer
needed to initiate the PCI bus scans, as the acpi_pci_root_driver
does that.

However, to maintain backward compatibility with non-ACPI capable
PROMs, none of the current 'fixup' code can been deleted, though
much restructuring has been done. For example, the bulk of the code
in io_common.c is relocated code that is now common regardless
of what PROM is running, while io_acpi_init.c and io_init.c contain
routines specific to an ACPI or non ACPI capable PROM respectively.

A new pci bus fixup platform vector has been created to provide
a hook for invoking platform specific bus fixup from pcibios_fixup_bus().

The size of io_space[] has been increased to support systems with
large IO configurations.

From a2302c68d923537436b1114aa207787c1a31bd50 Mon Sep 17 00:00:00 2001
From: John Keller <jpk@sgi.com>
Date: Wed, 4 Oct 2006 16:49:52 -0500
Subject: Altix: Initial ACPI support - ROM shadowing.

Support a shadowed ROM when running with an ACPI capable PROM.

Define a new dev.resource flag IORESOURCE_ROM_BIOS_COPY to
describe the case of a BIOS shadowed ROM, which can then
be used to avoid pci_map_rom() making an unneeded call to
pci_enable_rom().

Subject: pci/i386: style cleanups

Mostly CodingStyle cleanups for arch/i386/pci/i386.c:
- fit in 80 columns;
- use a #defined value instead of an inline constant;
Also change one resource_size_t (DBG) printk from %08lx to %lx since
it can be more than 32 bits (more than 8 hexits).

ioremap must be balanced by an iounmap and failing to do so can result
in a memory leak.

Tested (compilation only):
- using allmodconfig
- making sure the files are compiling without any warning/error due to
new changes

Subject: [ARM] 3967/1: xsc3: make branch predication configurable on xsc3

Remove BTB_ENABLE from proc-xsc3.S

On some early revisions of xsc3 enabling the branch target buffer can cause
crashes, see erratum #42.

Subject: Revert "ACPI: SCI interrupt source override"

This reverts commit 281ea49b0c294649a6de47a6f8fbe5611137726b,
which broke ACPI Interrupt source overrides that move
the SCI from one IRQ in PIC mode to another in IOAPIC mode.

If the SCI shared an interrupt line with another device,
this would result in a "irq 18: nobody cared" type failure.

From afe4b25e7d9260d85fccb2d13c9933a987bdfc8a Mon Sep 17 00:00:00 2001
From: Lennert Buytenhek <buytenh@wantstofly.org>
Date: Sun, 3 Dec 2006 18:51:14 +0100
Subject: [ARM] 3881/4: xscale: clean up cp0/cp1 handling

XScale cores either have a DSP coprocessor (which contains a single
40 bit accumulator register), or an iWMMXt coprocessor (which contains
eight 64 bit registers.)

Because of the small amount of state in the DSP coprocessor, access to
the DSP coprocessor (CP0) is always enabled, and DSP context switching
is done unconditionally on every task switch.  Access to the iWMMXt
coprocessor (CP0/CP1) is enabled only when an iWMMXt instruction is
first issued, and iWMMXt context switching is done lazily.

CONFIG_IWMMXT is supposed to mean 'the cpu we will be running on will
have iWMMXt support', but boards are supposed to select this config
symbol by hand, and at least one pxa27x board doesn't get this right,
so on that board, proc-xscale.S will incorrectly assume that we have a
DSP coprocessor, enable CP0 on boot, and we will then only save the
first iWMMXt register (wR0) on context switches, which is Bad.

This patch redefines CONFIG_IWMMXT as 'the cpu we will be running on
might have iWMMXt support, and we will enable iWMMXt context switching
if it does.'  This means that with this patch, running a CONFIG_IWMMXT=n
kernel on an iWMMXt-capable CPU will no longer potentially corrupt iWMMXt
state over context switches, and running a CONFIG_IWMMXT=y kernel on a
non-iWMMXt capable CPU will still do DSP context save/restore.

These changes should make iWMMXt work on PXA3xx, and as a side effect,
enable proper acc0 save/restore on non-iWMMXt capable xsc3 cores such
as IOP13xx and IXP23xx (which will not have CONFIG_CPU_XSCALE defined),
as well as setting and using HWCAP_IWMMXT properly.

From f90bb153b1493719d18b4529a46ebfe43220ea6c Mon Sep 17 00:00:00 2001

Subject: [POWERPC] Make pci_read_irq_line the default

This patch reworks the way IRQs are fixed up on PCI for arch powerpc.

It makes pci_read_irq_line() called by default in the PCI code for
devices that are probed, and add an optional per-device fixup in
ppc_md for platforms that really need to correct what they obtain
from pci_read_irq_line().

It also removes ppc_md.irq_bus_setup which was only used by pSeries
and should not be needed anymore.

I've also removed the pSeries s7a workaround as it can't work with
the current interrupt code anyway. I'm trying to get one of these
machines working so I can test a proper fix for that problem.

I also haven't updated the old-style fixup code from 85xx_cds.c
because it's actually buggy :) It assigns pci_dev->irq hard coded
numbers which is no good with the new IRQ mapping code. It should
at least use irq_create_mapping(NULL, hard_coded_number); and possibly
also set_irq_type() to set them as level low.

Subject: [POWERPC] Remove ppc_md.pci_map_irq & ppc_swizzle for ARCH=powerpc

These were inherited from ARCH=ppc, but are not needed since parsing of interrupts
should be done via the of_* functions (who can do swizzling). If we ever need to
do non-standard swizzling on bridges without a device-node, then we might add
back a slightly different version of ppc_md.pci_swizzle but for now, that is not
the case.

I removed the couple of calls for these in 83xx. If that breaks something, then
there is a problem with the device-tree on these.

Subject: [POWERPC] Generic DCR infrastructure

This patch adds new dcr_map/dcr_read/dcr_write accessors for DCRs that
can be used by drivers to transparently address either native DCRs or
memory mapped DCRs. The implementation for memory mapped DCRs is done
after the binding being currently worked on for SLOF and the Axon
chipset. This patch enables it for the cell native platform

Subject: [POWERPC] Support for DCR based MPIC

This patch implements support for DCR based MPIC implementations. Such
implementations have the MPIC_USES_DCR flag set and don't use the phys_addr
argument of mpic_alloc (they require a valid dcr mapping in the device node)

This version of the patch can use a little bif of cleanup still (I can
probably consolidate rb->dbase/doff, at least once I'm sure on how the
hardware is actually supposed to work vs. possible simulator issues) and
it should be possible to build a DCR-only version of the driver. I need
to cleanup a bit the CONFIG_* handling for that and probably introduce
CONFIG_MPIC_MMIO and CONFIG_MPIC_DCR.

Subject: [POWERPC] Improve MPIC driver auto-configuration from DT

This patch applies on top of the MPIC DCR support. It makes the MPIC
driver capable of a lot more auto-configuration based on the device-tree,
for example, it can retreive it's own physical address if not passed as
an argument, find out if it's DCR or MMIO mapped, and set the BIG_ENDIAN
flag automatically in the presence of a "big-endian" property in the
device-tree node.

From 7eebde700fe6fd6573e80bd8e5ed82b4ae705575 Mon Sep 17 00:00:00 2001
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
Date: Sat, 11 Nov 2006 17:24:59 +1100
Subject: [POWERPC] Souped-up of_platform_device support

This patch first splits of_device.c and of_platform.c, the later containing
the bits relative to of_platform_device's. On the "breaks" side of things,
drivers uisng of_platform_device(s) need to include asm/of_platform.h now
and of_(un)register_driver is now of_(un)register_platform_driver.

In addition to a few utility functions to locate of_platform_device(s),
the main new addition is of_platform_bus_probe() which allows the platform
code to trigger an automatic creation of of_platform_devices for a whole
tree of devices.

The function acts based on the type of the various "parent" devices encountered
from a provided root, using either a default known list of bus types that can be
"probed" or a passed-in list. It will only register devices on busses matching
that list, which mean that typically, it will not register PCI devices, as
expected (since they will be picked up by the PCI layer).

This will be used by Cell platforms using 4xx-type IOs in the Axon bridge
and can be used by any embedded-type device as well.

Subject: [POWERPC] Refactor 64 bits DMA operations

This patch completely refactors DMA operations for 64 bits powerpc. 32 bits
is untouched for now.

We use the new dev_archdata structure to add the dma operations pointer
and associated data to struct device. While at it, we also add the OF node
pointer and numa node. In the future, we might want to look into merging
that with pci_dn as well.

The old vio, pci-iommu and pci-direct DMA ops are gone. They are now replaced
by a set of generic iommu and direct DMA ops (non PCI specific) that can be
used by bus types. The toplevel implementation is now inline.

Subject: [POWERPC] Add DMA ops support for of_platform_device to Cell

This patch adds a bus device notifier to the of_platform bus type on
cell to setup the DMA operations for of_platform_devices. We currently
use the PCI operations as Cell use a special version of them that
happens to be suitable for our needs.

Subject: [POWERPC] Resolve the parent address of a PCI bus range

When parsing the OF "ranges" properties of PCI host busses to determine
the mapping of a PCI bus, we need to translate the "parent" address using
the prom_parse.c routines in order to obtain a CPU physical address.

This wasn't necessary while PCI busses were always at the root of the
device-tree but this is no longer the case on Cell where they can be
anywhere in the tree.

Subject: [POWERPC] Resolve the BUID for RTAS PCI config space accesses

The BUID is the first entry of a PCI host bridge "reg" property.

Now that PCI busses can be anywhere in the device-tree, we need to
fully translate the value there to a CPU physical address before
we can use it with RTAS.

Subject: [POWERPC] Add "parent" struct device for PCI host bridges

Add a "parent" struct device to our PCI host bridge data structure so that
PCI can be rooted off another device in sysfs.

Note that arch/ppc doesn't use it, only arch/powerpc, though it's available
for both 32 and 64 bits.

Subject: [POWERPC] Generic OF platform driver for PCI host bridges.

When enabled in Kconfig, it will pick up any of_platform_device
matching it's match list (currently type "pci", "pcix", "pcie",
or "ht" and setup a PHB for it.

Platform must provide a ppc_md.pci_setup_phb() for it to work
(for doing the necessary initialisations specific to a given PHB
like setting up the config space ops).

It's currently only available on 64 bits as the 32 bits PCI code
can't quite cope with it in it's current form. I will fix that
later.

Subject: [POWERPC] Allow hooking of PCI MMIO & PIO accessors on 64 bits

This patch reworks the way iSeries hooks on PCI IO operations (both MMIO
and PIO) and provides a generic way for other platforms to do so (we
have need to do that for various other platforms).

While reworking the IO ops, I ended up doing some spring cleaning in
io.h and eeh.h which I might want to split into 2 or 3 patches (among
others, eeh.h had a lot of useless stuff in it).

A side effect is that EEH for PIO should work now (it used to pass IO
ports down to the eeh address check functions which is bogus).

Also, new are MMIO "repeat" ops, which other archs like ARM already had,
and that we have too now: readsb, readsw, readsl, writesb, writesw,
writesl.

In the long run, I might also make EEH use the hooks instead
of wrapping at the toplevel, which would make things even cleaner and
relegate EEH completely in platforms/iseries, but we have to measure the
performance impact there (though it's really only on MMIO reads)

Since I also need to hook on ioremap, I shuffled the functions a bit
there. I introduced ioremap_flags() to use by drivers who want to pass
explicit flags to ioremap (and it can be hooked). The old __ioremap() is
still there as a low level and cannot be hooked, thus drivers who use it
should migrate unless they know they want the low level version.

The patch "arch provides generic iomap missing accessors" (should be
number 4 in this series) is a pre-requisite to provide full iomap
API support with this patch.

Subject: [POWERPC] Cell "Spider" MMIO workarounds

This patch implements a workaround for a Spider PCI host bridge bug
where it doesn't enforce some of the PCI ordering rules unless some
manual manipulation of a special register is done. In order to be
fully compliant with the PCI spec, I do this on every MMIO read
operation.

Subject: [POWERPC] Add an optional offset to direct DMA on 64 bits

This patch adds an optional global offset that can be added to DMA addresses
when using the direct DMA operations.

That brings it a step closer to the 32 bits direct DMA operations, and makes
it useable on Cell when the MMU is disabled and we are using a spider
southbridge.

Subject: [POWERPC] Make direct DMA use node local allocations

This patch makes dma_alloc_coherent() use node local allocation when
using the direct DMA ops. The node is obtained from the new device
extension. If no such extension is present, the current node is used.

Subject: [POWERPC] Make cell use direct DMA ops

Now that the direct DMA ops supports an offset, we use that instead
of defining our own.

Subject: [POWERPC] Cell iommu support

This patch adds full cell iommu support (and iommu disabled mode).

It implements mapping/unmapping of iommu pages on demand using the
standard powerpc iommu framework.  It also supports running with
iommu disabled for machines with less than 2GB of memory.  (The
default is off in that case, though it can be forced on with the
kernel command line option iommu=force).

Subject: [POWERPC] Remove ioremap64 and fixup_bigphys_addr

In order to suppose platforms with devices above 4Gb on 32 bits platforms
with a >32 bits physical address space, we used to have a special ioremap64
along with a fixup routine fixup_bigphys_addr.

This shouldn't be necessary anymore as struct resource now supports 64 bits
addresses even on 32 bits archs. This patch enables that option when
CONFIG_PHYS_64BIT is set and removes ioremap64 and fixup_bigphys_addr.

This is a preliminary work for the upcoming merge of 32 and 64 bits io.h

Subject: [POWERPC] Merge 32 and 64 bits asm-powerpc/io.h

powerpc: Merge 32 and 64 bits asm-powerpc/io.h

The rework on io.h done for the new hookable accessors made it easier,
so I just finished the work and merged 32 and 64 bits io.h for arch/powerpc.

arch/ppc still uses the old version in asm-ppc, there is just too much gunk
in there that I really can't be bothered trying to cleanup.

Subject: [POWERPC] Make soft_enabled irqs preempt safe

Rewrite local_get_flags and local_irq_disable to use r13 explicitly,
to avoid the risk that gcc will split get_paca()->soft_enabled into a
sequence unsafe against preemption.  Similar care in local_irq_restore.

Subject: [POWERPC] Make pci_read_irq_line the default on mpc7448hpc2 board

The following patch adds a tsi108/9 pci interrupt controller host.
On mpc7448hpc2 board, pci_irq_fixup function is removed, which makes the
pci_read_irq_line be the default pci irq fixup.

Per email discussion, it appears that rtas_stop_self()
and pSeries_mach_cpu_die() should not be compiled if
CONFIG_HOTPLUG_CPU is not defined. This patch adds
#ifdefs around these bits of code.

Subject: [POWERPC] Small clarification of initrd handling

This patch makes the handling of the initrd (or initramfs) in the
zImage wrapper a little easier to follow.  Instead of passing the
initrd addresses out from prep_kernel() via the cryptic a1 and a2
parameters, use the global struct add_range, 'initrd'.  prep_kernel()
already passes information through the 'vmlinux' addr_range struct, so
this seems like a reasonable extension.

Some comments also clarify the logic with prep_kernel(): we use an
initrd included in the zImage if present, otherwise we use an initrd
passed in by the bootloader in the a1 and a2 parameters (yaboot, at
least, uses this mechanism to pass an initrd).

Subject: [POWERPC] Cleanup zImage handling of kernel entry with flat device
 tree

This makes 2 changes to clean up the flat device tree handling
logic in the zImage wrapper.

First, there were two callbacks from the dt_ops structure used for
producing a final flat tree to pass to the kerne: dt_ops.ft_pack()
which packed the flat tree (possibly a no-op) and dt_ops.ft_addr()
which retreived the address of the final blob.  Since they were only
ever called together, this patch combines the two into a single new
callback, dt_ops.finalize().  This new callback does whatever
platform-dependent things are necessary to produce a final flat device
tree blob, and returns the blob's addres.

Second, the current logic calls the kernel with a flat device tree if
one is build into the zImage wrapper, otherwise it boots the kernel
with a PROM pointer, expecting the kernel to copy the OF device tree
itself.  This approach precludes the possibility of the platform
wrapper code building a flat device tree from whatever
platform-specific information firmware provides.  Thus, this patch
takes the more sensible approach of invoking the kernel with a flat
tree if the dt_ops.finalize callback provides one (by whatever means).

So, the dt_ops.finalize callback can be NULL, or can be a function
which returns NULL.  In either case, the zImage wrapper logic assumes
that this is a platform with OF and invokes the kernel accordingly.

Before this patch some files used "0x%llx" and other used "%llx" which is
inconsistent and potentially confusing. A user might assume "%llx" numbers
were decimal if they happened to not contain any a-f digits. This change
will break any code cannot tolerate a leading 0x in the file contents. The

some scripts which access these files. This risk is deemed acceptable for

Subject: [POWERPC] spufs: Add /lslr, /dma_info and /proxydma files

The /lslr file gives read access to the SPU_LSLR register in hex; 0x3fff
for example The /dma_info file provides read access to the SPU Command
Queue in a binary format. The /proxydma_info files provides read access
access to the Proxy Command Queue in a binary format. The spu_info.h
file provides data structures for interpreting the binary format of
/dma_info and /proxydma_info.

Subject: [POWERPC] spufs: Remove /spu_tag_mask file

This patch removes the /spu_tag_mask file from spufs. The data provided by
this file is also available from the /dma_info file in the dma_info_mask
of the spu_dma_info struct.

The file was intended to be used by gdb, but that never used it, and
now it has been replaced with the more verbose dma_info file.

Subject: [POWERPC] spufs: Implement /mbox_info, /ibox_info, and /wbox_info.

This patch implements read only access to

/mbox_info - SPU Write Outbound Mailbox
/ibox_info - SPU Write Outbound Interrupt Mailbox
/wbox_info - SPU Read Inbound Mailbox

These files are used by gdb in order to look into the current mailbox
queues without changing the contents at the same time. They are
not meant for general programming use, since the access requires
a context save and is therefore rather slow.

It would be good to complement this patch with one that adds
write support as well.

Subject: [POWERPC] spufs: Read from signal files only if data is there

We need to check the channel count of the signal notification registers
before reading them, because it can be undefined when the count is
zero. In order to read count and data atomically, we read from the
saved context.

This patch uses spu_acquire_saved() to force a context save before a
/signal1 or /signal2 read. Because of this it is no longer necessary to
have backing_ops and hw_ops versions of this function so they have been
removed.

Regular applications should not rely on reading this register
to be fast, as it's conceptually a write-only file from the PPE
perspective.

Subject: [POWERPC] spufs: Fix missing stop-and-signal

When there is pending signals, current spufs_run_spu() always returns
-ERESTARTSYS and it is called again automatically.
But, if spe already stopped by stop-and-signal or halt instruction,
returning -ERESTARTSYS makes stop-and-signal/halt lost and
spu run over the end-point.

For your convenience, I attached a sample code to restage this bug.
If there is no bug, printed NPC will be 0x4000.

Subject: [POWERPC] spufs: Avoid user-triggered oops in ptrace

When one of the spufs files is mapped into a process address
space, regular users can use ptrace to attempt accessing
them with access_process_vm(). With the way that the
mappings currently work, this likely causes an oops.

Setting the vm_flags to VM_IO makes sure that ptrace can
not access them but returns an error code. This is not
the perfect solution in case of the local store mapping,
but it fixes the oops in a well-defined way.

Also remove leftover VM_RESERVED flags in spufs.  The
VM_RESERVED flag is on it's way out and not checked by
the memory managment code anymore.

and guarded mapping, which resulted in a serious performance
degradation.

Subject: [POWERPC] spufs: Add runcntrl read accessors

This change adds a read accessor for the SPE problem-state run control
register.

This is required for for applying (userspace) changes made to the run
control register while the SPE is stopped - simply asserting the master
run control bit is not sufficient. My next patch for isolated-mode
setup requires this.

Subject: [POWERPC] spufs: Load isolation kernel from spu_run

In order to fit with the "don't-run-spus-outside-of-spu_run" model, this
patch starts the isolated-mode loader in spu_run, rather than
spu_create. If spu_run is passed an isolated-mode context that isn't in
isolated mode state, it will run the loader.

This fixes potential races with the isolated SPE app doing a
stop-and-signal before the PPE has called spu_run: bugzilla #29111.
Also (in conjunction with a mambo patch), this addresses #28565, as we
always set the runcntrl register when entering spu_run.

It is up to libspe to ensure that isolated-mode apps are cleaned up
after running to completion - ie, put the app through the "ISOLATE EXIT"
state (see Ch11 of the CBEA).

Subject: [POWERPC] cell: Move PMU-related stuff to
 include/asm-powerpc/cell-pmu.h

Move some PMU-related macros and function prototypes from cbe_regs.h
and pmu.h in arch/powerpc/platforms/cell/ to a new header at
include/asm-powerpc/cell-pmu.h

This is cleaner to use from the oprofile code, since that sits in
arch/powerpc/oprofile, not in the cell platform directory.

Subject: [POWERPC] cell: Add routines for managing PMU interrupts

The following routines are added to arch/powerpc/platforms/cell/pmu.c:
 cbe_clear_pm_interrupts()
 cbe_enable_pm_interrupts()
 cbe_disable_pm_interrupts()
 cbe_query_pm_interrupts()
 cbe_pm_irq()
 cbe_init_pm_irq()

This also adds a routine in arch/powerpc/platforms/cell/interrupt.c and
some macros in cbe_regs.h to manipulate the IIC_IR register:
 iic_set_interrupt_routing()

Subject: [POWERPC] cell: Add oprofile support

Add PPU event-based and cycle-based profiling support to Oprofile for Cell.

Oprofile is expected to collect data on all CPUs simultaneously.
However, there is one set of performance counters per node.  There are
two hardware threads or virtual CPUs on each node.  Hence, OProfile must
multiplex in time the performance counter collection on the two virtual
CPUs.

The multiplexing of the performance counters is done by a virtual
counter routine.  Initially, the counters are configured to collect data
on the even CPUs in the system, one CPU per node.  In order to capture
the PC for the virtual CPU when the performance counter interrupt occurs
(the specified number of events between samples has occurred), the even
processors are configured to handle the performance counter interrupts
for their node.  The virtual counter routine is called via a kernel
timer after the virtual sample time.  The routine stops the counters,
saves the current counts, loads the last counts for the other virtual
CPU on the node, sets interrupts to be handled by the other virtual CPU
and restarts the counters, the virtual timer routine is scheduled to run
again.  The virtual sample time is kept relatively small to make sure
sampling occurs on both CPUs on the node with a relatively small
granularity.  Whenever the counters overflow, the performance counter
interrupt is called to collect the PC for the CPU where data is being
collected.

The oprofile driver relies on a firmware RTAS call to setup the debug bus
to route the desired signals to the performance counter hardware to be
counted.  The RTAS call must set the routing registers appropriately in
each of the islands to pass the signals down the debug bus as well as
routing the signals from a particular island onto the bus.  There is a
second firmware RTAS call to reset the debug bus to the non pass thru
state when the counters are not in use.

Subject: [POWERPC] Distinguish POWER6 partition modes and tell userspace

This adds code to look at the properties firmware puts in the device
tree to determine what compatibility mode the partition is in on
POWER6 machines, and set the ELF aux vector AT_HWCAP and AT_PLATFORM
entries appropriately.

Specifically, we look at the cpu-version property in the cpu node(s).
If that contains a "logical" PVR value (of the form 0x0f00000x), we
call identify_cpu again with this PVR value.  A value of 0x0f000001
indicates the partition is in POWER5+ compatibility mode, and a value
of 0x0f000002 indicates "POWER6 architected" mode, with various
extensions disabled.  We also look for various other properties:
ibm,dfp, ibm,purr and ibm,spurr.

Subject: [POWERPC] powerpc: Workaround for of_platform without "reg" nor
 "dcr-reg"

Devices with no "reg" nor "dcr-reg" property are given a bus_id which
is the node name alone. This means that if more than one such device
with the same names are present in the system, sysfs will have
collisions when creating the symlinks and will fail registering the
devices.

This works around that problem by assigning successive numbers to such
devices.

Subject: [POWERPC] coredump: Add SPU elf notes to coredump.

This patch adds SPU elf notes to the coredump. It creates a separate note
for each of /regs, /fpcr, /lslr, /decr, /decr_status, /mem, /signal1,
/signal1_type, /signal2, /signal2_type, /event_mask, /event_status,
/mbox_info, /ibox_info, /wbox_info, /dma_info, /proxydma_info, /object-id.

A new macro, ARCH_HAVE_EXTRA_NOTES, was created for architectures to
specify they have extra elf core notes.

A new macro, ELF_CORE_EXTRA_NOTES_SIZE, was created so the size of the
additional notes could be calculated and added to the notes phdr entry.

A new macro, ELF_CORE_WRITE_EXTRA_NOTES, was created so the new notes
would be written after the existing notes.

The SPU coredump code resides in spufs. Stub functions are provided in the
kernel which are hooked into the spufs code which does the actual work via
register_arch_coredump_calls().

A new set of __spufs_<file>_read/get() functions was provided to allow the
coredump code to read from the spufs files without having to lock the
SPU context for each file read from.

Subject: [POWERPC] cell: hard disable interrupts in power_save()

With soft-disabled interrupts in power_save, we can
still get external exceptions on Cell, even if we are
in pause(0) a.k.a. sleep state.

When the CPU really wakes up through the 0x100 (system reset)
vector, while we have already started processing the 0x500
(external) exception, we get a panic in unrecoverable_exception()
because of the lost state.

This occurred in Systemsim for Cell, but as far as I can see,
it can theoretically occur on any machine that uses the
system reset exception to get out of sleep state.

Subject: [POWERPC] Fix sparse warning in xmon Cell code

My patch to add spu helpers to xmon (a898497088f46252e6750405504064e2dce53117)
introduced a few sparse warnings, because I was dereferencing an __iomem
pointer.

I think the best way to handle it is to actually use the appropriate in_beXX
functions. Need to rejigger the DUMP macro a little to accomodate that.

After stopping spus in xmon I often find myself trawling through the

code actually knows what's running, so let's print it out to save
the user some futzing.

Subject: [POWERPC] Add a sd command (spu dump) to xmon to dump spu local store

Add a command to xmon to dump the memory of a spu's local store.
This mimics the 'd' command which dumps regular memory, but does
a little hand holding by taking the user supplied address and
finding that offset in the local store for the specified spu.

This makes it easy for example to look at what was executing on a spu:

1:mon> ss
...
Stopped spu 04 (was running)
...
1:mon> sf 4
Dumping spu fields at address c0000000019e0a00:
...
  problem->spu_npc_RW     = 0x228
...
1:mon> sd 4 0x228
d000080080318228 01a00c021cffc408 4020007f217ff488  |........@ ..!...|

Aha, 01a00c02, which is of course rdch $2,$ch24 !

--

Updated to only do the setjmp goo around the spu access, and not
around prdump because it does its own (via mread).

Also the num variable is now common between sf and sd, so you don't
have to keep typing the spu number in if you're repeating commands
on the same spu.

Subject: [POWERPC] Prepare for spu disassembly in xmon

In order to do disassembly of spu binaries in xmon, we need to abstract
the disassembly function from ppc_inst_dump.

We do this by making the actual disassembly function a function pointer
that we pass to ppc_inst_dump(). To save updating all the callers, we
turn ppc_inst_dump() into generic_inst_dump() and make ppc_inst_dump()
a wrapper which always uses print_insn_powerpc().

Currently we pass the dialect into print_insn_powerpc(), but we always
pass 0 - so just make it a local.

Subject: [POWERPC] Import spu disassembly code into xmon

This patch imports and munges the spu disassembly code from binutils.

All files originated from version 1.1 in binutils cvs.
 * spu.h, spu-insns.h and spu-opc.c are unchanged except for pathnames.
 * spu-dis.c has been edited heavily:
   * use printf instead of info->fprintf_func and similar.
   * pass the instruction in rather than reading it.
   * we have no equivalent to symbol_at_address_func, so we just assume
     there is never a symbol at the address given.

+-=-=-= OPCODE =-=-=-
+
+OPCODE field specifies the most significant 11bit of the instruction. Some formats don't have 11bits for opcode field, and in this
+case, bit field other than op are defined as 0s. For example, opcode of fma instruction which is RRR format is defined as 0x700,
+since 0x700 -> 11'b11100000000, this means opcode is 4'b1110, and other 7bits are defined as 7'b0000000.

+
+Note that RRR instructions have the names for RC and RT reversed from
+what's in the ISA, in order to put RT in the same position it appears
+for other formats.
+
+-=-=-= DEPENDENCY =-=-=-
+
+DEPENDENCY filed consists of 5 digits. This represents which register is used as source and which register is used as target.
+The first(most significant) digit is always 0. Then it is followd by RC, RB, RA and RT digits.
+If the digit is 0, this means the corresponding register is not used in the instruction.
+If the digit is 1, this means the corresponding register is used as a source in the instruction.
+If the digit is 2, this means the corresponding register is used as a target in the instruction.
+If the digit is 3, this means the corresponding register is used as both source and target in the instruction.
+For example, fms instruction has 00113 as the DEPENDENCY field. This means RC is not used in this operation, RB and RA are
+used as sources and RT is the target.
+
+-=-=-= PIPE =-=-=-
+
+This field shows which execution pipe is used for the instruction
+
+pipe0 execution pipelines:
+	FP6	SP floating pipeline
+	FP7	integer operations executed in SP floating pipeline
+	FPD	DP floating pipeline
+	FX2	FXU pipeline
+	FX3	Rotate/Shift pipeline

Subject: [POWERPC] Make xmon disassembly optional

While adding spu disassembly support it struck me that we're actually
carrying quite a lot of code around, just to do disassembly in the case
of a crash.

While on large systems it's not an issue, on smaller ones it might be
nice to have xmon - but without the weight of the disassembly support.
For a Cell build this saves ~230KB (!), and for pSeries ~195KB.

We still support the 'di' and 'sdi' commands, however they just dump
the instruction in hex.

Move the definitions into a header to clean xmon.c just a tiny bit.

Subject: [POWERPC] Import updated version of ppc disassembly code for xmon

This includes:
 * version 1.24 of ppc-dis.c
 * version 1.88 of ppc-opc.c
 * version 1.23 of ppc.h

I can't vouch for the accuracy etc. of these changes, but it brings
us into line with binutils - and from a cursory test appears to work
fine.

Subject: [POWERPC] cell: abstract spu management routines

This adds a platform specific spu management abstraction and the coresponding
routines to support the IBM Cell Blade.  It also removes the hypervisor only
resources that were included in struct spu.

Three new platform specific routines are introduced, spu_enumerate_spus(),
spu_create_spu() and spu_destroy_spu().  The underlying design uses a new
type, struct spu_management_ops, to hold function pointers that the platform
setup code is expected to initialize to instances appropriate to that platform.

For the IBM Cell Blade support, I put the hypervisor only resources that were
in struct spu into a platform specific data structure struct spu_pdata.

Subject: [POWERPC] ps3: add lpar addressing

Adds some needed bits for a config option PS3_USE_LPAR_ADDR that disables
the PS3 lpar address translation mechanism.  This is a currently needed
workaround for limitations in the design of the generic cell spu support.

Subject: [POWERPC] update cell_defconfig for ps3 support

In the common cell kernel, I want to have ps3 enabled
to find potential bugs at compile-time.
Also enable SPU disassembly in xmon.

Subject: [POWERPC] powerpc: Make 970MP detectable by oprofile

Change the oprofile_cpu_type in cputables.c to be ppc64/970MP.  Oprofile
needs to distinquish the MP from other 970 processors so it can add some
new counters specific to the 970MP.

Currently, we only send a sigtrap if the current task is being ptraced.
This is somewhat inconsistant, and it breaks utrace support in fedora.
Removing the check should do the right thing in all cases.

It may be desireable to build a kernel for cell without
spufs, e.g. as the initial kboot kernel. This requires
that the SPU specific parts of the core dump and the xmon
code depend on CONFIG_SPU_BASE instead of CONFIG_PPC_CELL.

Subject: [POWERPC] ps3: multiplatform build fixes

A few code paths need to check whether or not they are running
on the PS3's LV1 hypervisor before making hcalls. This introduces
a new firmware feature bit for this, FW_FEATURE_PS3_LV1.

Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES,
FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time,
which is a bug. The same problem can also happen for (PPC_ISERIES &&
!PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I
introduce a new CONFIG_PPC_NATIVE option that is set when at least
one platform is selected that can run without a hypervisor and then
turns the firmware feature check into a run-time option.

The new cell oprofile support that was recently merged does not
work on hypervisor based platforms like the PS3, therefore make
it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change
if we get oprofile support for PS3.

Subject: [POWERPC] ps3: add a default zImage target

It's currently not possible to build the default zImage
target if PS3 is the only selected platform. This is
a hack to fall back to building the pseries style
zImage, so the build is successful. This will probably
change in the future, if someone writes a PS3 specific
boot wrapper.

Subject: [POWERPC] pSeries/kexec: Fix for interrupt distribution

This allows any secondary CPU thread also to become boot cpu for
POWER5.  The patch is required to solve kdump boot issue when the
kdump kernel is booted with parameter "maxcpus=1".  XICS init code
tries to match the current boot cpu id with "reg" property in each CPU
node in the device tree.  But CPU node is created only for primary
thread CPU ids and "reg" property only reflects primary CPU ids.  So
when a kernel is booted on a secondary cpu thread above condition will
never meet and the default distribution server is left as zero.  This
leads to route the interrupts to CPU 0, but which is not online at
this time.

We use ibm,ppc-interrupt-server#s to check for both primary and
secondary CPU ids.  Accordingly default distribution server value is
initialized from "ibm,ppc-interrupt-gserver#s" property.  We loop
through ibm,ppc-interrupt-gserver#s property to find the global
distribution server from the last entry that matches with boot cpuid.

Subject: [POWERPC] Put mpc52xx support file in platforms/52xx

platforms/embedded6xx is probably going away, and 52xx boards need
some extra support the 52xx interrupt controller and DMA engine
anyway.  It makes sense to group all the 52xx bits into a single path.

Subject: [POWERPC] Move Efika support files into platforms/52xx

The Efika board isn't different enough from other 52xx based boards to
justify a separate platform.  This patch merges it with the support
code for all other 52xx based boards.

Subject: [POWERPC] Separate IRQ config / register set from main header

There is no need to expose these settings outside the scope
of the interrupt controller code itself.

Subject: [POWERPC] Add common routines for 52xx support in arch/powerpc

Adds utility routines used by 52xx device drivers and board support
code.  Main functionality is to add device nodes to the of_platform_bus,
retrieve the IPB bus frequency, and find+ioremap device registers.

Cure the damage done by the former PCI debug printks fix for the case
of 64-bit resources (commit 685143ac1f7a579a3fac9c7f2ac8f82e95af6864)
which broke it for the plain vanilla 32-bit resources...

Subject: [ARM] 3972/1: AT91: Update board.h

Replace the 'is_b' variable with 'slot_b' in at91_mmc_data.
Also add the new 'chipselect' variable for CF/PCMCIA and 'bus_width_16'
variable for NAND.

This (and previous patches) will unfortunately break the current MMC,
USB Gadget and PCMCIA drivers.  Updates and fixes for those drivers will
be submitted to the various subsystem maintainers.

Subject: [S390] remove salipl memory detection.

The SALIPL entry point has an needless memory detection routine as we
later check the memory size again. The SALIPL code also uses diagnose
0x060 if we are running under VM, but this diagnose is not compatible
with the 64 bit addressing mode. The solution is to get rid of this

Subject: [S390] Add ipl/reipl loadparm attribute.

If multiple kernel images are installed on one DASD, the loadparm can be used
to select the boot configuration. This patch introduces the following two new
sysfs attributes:

/sys/firmware/ipl/loadparm: shows loadparm of current system (ro)
/sys/firmware/reipl/ccw/loadparm: loadparm used for next reboot (rw)

Subject: [S390] Use diag instead of ccw reipl.

Since the diag 308 reipl method is superior to the ccw method, we should
use it whenever it is possible. We can do that, if the user has not
specified a new reipl ccw device and the system has been ipled from
a ccw device.

Subject: [S390] Reset infrastructure for re-IPL.

In case of re-IPL and diag308 doesn't work we have to reset all devices
manually and wait synchronously that each reset finished.
This patch adds the necessary infrastucture and the first exploiter of it.

Subsystems that need to add a function that needs to be called at re-IPL
may register/unregister this function via

struct reset_call {
	struct reset_call *next;
	void (*fn)(void);
};

void register_reset_call(struct reset_call *reset);
void unregister_reset_call(struct reset_call *reset);

When the registered function get called the context is:

- all cpus beside the current one are stopped
- all machine checks and interrupts are disabled
- prefixing is disabled
- a default machine check handler is available for use

The registered functions may not take any locks are sleep.

For the common I/O layer part of this patch:

Introduce a reset_call css_reset that does the following:
- clear all subchannels
- perform a rchp on all channel paths and wait for the resulting
  machine checks
This replaces the calls to clear_all_subchannels() and
cio_reset_channel_paths() for kexec and ccw reipl. reipl_ccw_dev() now
uses reipl_find_schid() to determine the subchannel id for a given
device id.
Also remove cio_reset_channel_paths() and friends since they are not
needed anymore.

Subject: [S390] cpcmd <-> __cpcmd calling issues

In case of reipl cpcmd gets called when all other cpus are not running
anymore. To prevent deadlocks change __cpcmd so that it doesn't take
any locks and call cpcmd or __cpcmd, whatever is correct in the current
context.

Subject: [S390] cpu shutdown rework

Let one master cpu kill all other cpus instead of sending an external
interrupt to all other cpus so they can kill themselves.
Simplifies reipl/shutdown functions a lot.

Subject: [S390] Misaligned wait PSW at memory detection.

If the memory detection code would ever reach the point where it would
load the wait psw, it would generate a specification exception and the
system would crash at ipl time. This is because of a misaligned wait
psw. It needs to be on a double word boundary instead of a word
boundary.

Subject: [S390] Use diag260 for memory size detection.

Avoid the tprot loop if diag260 works and reports that there are no
holes in memory. The tprot instruction can lead to a significant delay
in the ipl process if the virtual guest has a lot of memory and the
host is under memory pressure.

Subject: [S390] Add dynamic size check for usercopy functions.

Use a wrapper for copy_to/from_user to chose the best usercopy method.
The mvcos instruction is better for sizes greater than 256 bytes, if
mvcos is not available a page table walk is better for sizes greater
than 1024 bytes. Also removed the redundant copy_to/from_user_std_small
functions.

Subject: [S390] lockdep: show held locks when showing a stackdump

Follow i386/x86_64:
lockdep can be used to print held locks when printing a
backtrace. This can be useful when debugging things like
'scheduling while atomic' asserts.

Subject: [S390] Memory detection fixes.

VMALLOC_END on 31bit should be 0x8000000UL instead of 0x7fffffffL.
The page mask which is used to make sure memory_end is on 4MB/2MB
boundary is wrong and not needed. Therefore remove it.
Make sure a vmalloc area does also exist and work on (future)
machines with 4TB and more memory.

Subject: [S390] Don't use small stacks when lockdep is used.

The lock dependency validator adds a bunch of extra stack frames to
the stack, which can cause stack overflows. Especially seen on 31 bit
where the small stack is only 4k.

Subject: [PATCH] m68knommu: remove __rom_end from 68360 startup code

Remove use of __rom_end symbol all together. This helps clean out the
miscellaneous symbols lying around in the m68knommu linker script.

Subject: [MIPS] Use SYSVIPC_COMPAT to fix various problems on N32

N32 SysV IPC system calls should use 32-bit compatible code.
arch/mips/kernel/linux32.c have similar compatible code for O32, but
ipc/compat.c seems more complete.  We can use it for both N32 and O32.

This patch should fix these problems (and other possible problems):

Subject: [MIPS] Unify csum_partial.S

The 32-bit version and 64-bit version are almost equal.  Unify them.  This
makes further improvements (for example, copying with parallel, supporting
PREFETCH, etc.) easier.

Subject: [POWERPC] ps3: add a default zImage target

Add a powerpc make target that can be loaded by the ps3 bootloader (kboot) and
set this as the default image to build for that platform.

Until the compressed zImage wrapper is made, this arranges for a stripped
vmlinux image to be built.

The support for the 52xx-based systems is now included under
CONFIG_CLASSIC32, since the 52xx chips have a 603e-based core.

Subject: WorkQueue: Fix up arch-specific work items where possible

Fix up arch-specific work items where possible to use the new work_struct and
delayed_work structs.

Three places that enqueue bits of their stack and then return have been marked
with #error as this is not permitted.

Subject: sh: Exception vector rework and SH-2/SH-2A support.

This splits out common bits from the existing exception handler for
use between SH-2/SH-2A and SH-3/4, and adds support for the SH-2/2A
exceptions.

Subject: sh: Configurable timer IRQ.

All of the various CPU subtypes currently hardcode TIMER_IRQ,
switch this to a config option in the few places we need this.

This allows further removal of hardcoded IRQ headers..

From 9a7ef6d59f9d4780ff5bc9c4d05266b52dcb9211 Mon Sep 17 00:00:00 2001
From: Paul Mundt <lethal@linux-sh.org>
Date: Mon, 20 Nov 2006 13:55:34 +0900
Subject: sh: Drop CPU subtype IRQ headers.

This drops the various IRQ headers that were floating around
and primarily providing hardcoded IRQ definitions for the
various CPU subtypes. This quickly got to be an unmaintainable
mess, made even more evident by the subtle breakage introduced
by the SH-2 and SH-2A changes.

Now that subtypes are able to register IRQ maps directly, just
rip all of the headers out.

Subject: sh: Preliminary support for SH-X2 MMU.

This adds some preliminary support for the SH-X2 MMU, used by
newer SH-4A parts (particularly SH7785).

This MMU implements a 'compat' mode with SH-X MMUs and an
'extended' mode for SH-X2 extended features. Extended features
include additional page sizes (8kB, 4MB, 64MB), as well as the
addition of page execute permissions.

The extended mode attributes are placed in a second data array,
which requires us to switch to 64-bit PTEs when in X2 mode.

With the addition of the exec perms, we also overhaul the mmap
prots somewhat, now that it's possible to handle them more
intelligently.

Subject: sh: Explicit endian selection support.

Previously big endian was simply assumed if little endian was
not set, which led to some cflags ordering issues. There's not
much point to not having a big endian option, so shove one in
a choice and wire it up in the Makefile.

This lets us clean up some of the cflags ordering while we're
at it.

From f0bc814cfbc212683c882e58b3d1afec6b3e3aa3 Mon Sep 17 00:00:00 2001
From: Stuart Menefy <stuart.menefy@st.com>
Date: Tue, 21 Nov 2006 11:16:57 +0900
Subject: sh: gcc4 support.

This fixes up the kernel for gcc4. The existing exception handlers
needed some wrapping for pt_regs access, acessing the registers
via a RELOC_HIDE() pointer.

The strcpy() issues popped up here too, so add -ffreestanding and
kill off the symbol export.

Subject: sh: Set up correct siginfo structures for page faults.

Remove the previous saving of fault codes into the thread_struct
as they are never used, and appeared to be inherited from x86.

Remove extra bits from the pmd structure and store a kernel logical
address rather than a physical address. This allows it to be directly
dereferenced. Another piece of wierdness inherited from x86.

Subject: sh: generic push-switch framework.

This adds support for a generic push switch framework. Adaptable for
various switches, including GPIO switches and the push switches commonly
found on Renesas debug boards.

This allows switch states to be trivially reported through sysfs.

Subject: sh: Fix syscall tracing ordering.

The implementation of system call tracing in the kernel has a
couple of ordering problems:

 - the validity of the system call number is checked before
   calling out to system call tracing code, and should be
   done after

 - the system call number used when tracing is the one the
   system call was invoked with, while the system call tracing
   code can legitimatly change the call number (for example
   strace permutes fork into clone)

This patch fixes both of these problems, and also reoders the
code slightly to make the direct path through the code the
common case.

Subject: sh: Drop name overload in dma-sh.

Pass along the dev_id from request_dma() all the way down,
rather than inserting an artificial name relating to the TEI
line that we were doing before.

This makes the line a bit less obvious, but dev_id is the proper
behaviour for this regardless.

Subject: sh: dma-api channel capability extensions.

This extends the SH DMA API for allowing handling of DMA
channels based off of their respective capabilities.

A couple of functions are added to the existing API,
the core bits are register_chan_caps() for registering
channel capabilities, and request_dma_bycap() for fetching
a channel dynamically based off of a capability set.

- * A brief note about the reasons for this API as it stands.
- *
- * For starters, the old ISA DMA API didn't work for us for a number of
- * reasons, for one, the vast majority of channels on the SH DMAC are
- * dual-address mode only, and both the new and the old DMA APIs are after the
- * concept of managing a DMA buffer, which doesn't overly fit this model very
- * well. In addition to which, the new API is largely geared at IOMMUs and
- * GARTs, and doesn't even support the channel notion very well.
- *
- * The other thing that's a marginal issue, is the sheer number of random DMA
- * engines that are present (ie, in boards like the Dreamcast), some of which
- * cascade off of the SH DMAC, and others do not. As such, there was a real
- * need for a scalable subsystem that could deal with both single and
- * dual-address mode usage, in addition to interoperating with cascaded DMACs.
- *
- * There really isn't any reason why this needs to be SH specific, though I'm
- * not aware of too many other processors (with the exception of some MIPS)
- * that have the same concept of a dual address mode, or any real desire to
- * actually make use of the DMAC even if such a subsystem were exposed
- * elsewhere.
- *
- * The idea for this was derived from the ARM port, which acted as an excellent
- * reference when trying to address these issues.
- *
- * It should also be noted that the decision to add Yet Another DMA API(tm) to
- * the kernel wasn't made easily, and was only decided upon after conferring
- * with jejb with regards to the state of the old and new APIs as they applied
- * to these circumstances. Philip Blundell was also a great help in figuring
- * out some single-address mode DMA semantics that were otherwise rather
- * confusing.

Subject: sh: Fixup 4K irq stacks.

There was a clobber issue with the register we were saving
the stack in, so we switch to a register that we handle in
the clobber list properly already.

This also follows the x86 changes for allowing the softirq
checks from hardirq context.

From: Paul Mundt <lethal@linux-sh.org>
Date: Mon, 27 Nov 2006 12:06:26 +0900
Subject: sh: Fixup various PAGE_SIZE == 4096 assumptions.

There were a number of places that made evil PAGE_SIZE == 4k
assumptions that ended up breaking when trying to play with
8k and 64k page sizes, this fixes those up.

The most significant change is the way we load THREAD_SIZE,
previously this was done via:

	mov	#(THREAD_SIZE >> 8), reg
	shll8	reg

to avoid a memory access and allow the immediate load. With
a 64k PAGE_SIZE, we're out of range for the immediate load
size without resorting to special instructions available in
later ISAs (movi20s and so on). The "workaround" for this is
to bump up the shift to 10 and insert a shll2, which gives a
bit more flexibility while still being much cheaper than a
memory access.

Subject: sh: More flexible + SH7780 earlyprintk SCIF support.

This makes the early printk support somewhat more flexible,
moving the port definition to a config option, and making the
port initialization configurable for sh-ipl+g users.

At the same time, this allows us to trivially wire up the
SH7780 SCIF0, so that's thrown in too more or less for free.

Subject: sh: Fix store queue bitmap end.

The end of the store queue bitmap is miscalculated when searching
for a free range in sq_remap(), missing the PAGE_SHIFT shift that's
done in sq_api_init(). This runs in to workloads where we can scan
beyond the end of the bitmap.

Spotted by Paul Jackson:

Subject: sh: Get the PGD right in oops case with 64-bit PTEs.

Previously this was using a static pgd shift in the reporting
code, simply flip this to PGDIR_SHIFT which does the right
thing depending on varying PTE magnitudes on the SH-X2 MMU.

While we're at it, and since it's been recently added, use
get_TTB() for fetching the TTB, rather than the open coded
instructions.

Subject: sh: Turn off IRQs around get_timer_offset() calls.

Since all of the sys_timer sources currently do this on their own
within the ->get_offset() path, it's more sensible to just have
the caller take care of it when grabbing xtime_lock. Incidentally,
this is more in line with what others (ie, ARM) are doing already.

This syncs up the SH clock framework with the linux/clk.h API,
for which there were only some minor changes required, namely
the clk_get() dev_id and subsequent callsites.

From bd156147eb63ae525e0ac67868e41a808f03c532 Mon Sep 17 00:00:00 2001
From: Paul Mundt <lethal@linux-sh.org>
Date: Fri, 1 Dec 2006 13:23:47 +0900
Subject: sh: dyntick infrastructure.

This adds basic NO_IDLE_HZ support to the SH timer API so timers
are able to wire it up. Taken from the ARM version, as it fit in
to our API with very few changes needed.

Since some header inclusion paths were cleaned up, compilation
broke. Add in the headers we need directly to build again.

From ea0f8feaa041f3ccec3d6b8ee51325b177daef06 Mon Sep 17 00:00:00 2001
From: Jamie Lenehan <lenehan@twibble.org>
Date: Wed, 6 Dec 2006 12:05:02 +0900
Subject: sh: sh775x/titan fixes for irq header changes.

The following moves the creation of IPR interupts into setup-7750.c
and updates a few other things to make it all work after the "Drop
CPU subtype IRQ headers" commit. It boots and runs fine on my titan
board.

 - adds an ipr_idx to the ipr_data and uses a function in the subtype
   code to calculate the address of the IPR registers

 - adds a function to enable individual interrupt mode for externals
   in the subtype code and calls that from the titan board code
   instead of doing it directly.

 - I changed the shift in the ipr_data to be the actual # of bits to
   shift, instead of the numnber / 4 - made it easier to match with
   the manual.

Subject: [PATCH] m68knommu: fix timer register access on 523x ColdFire
 platforms

The 523x timer TRR register is a full 32bits, the older register (on
other ColdFire parts) was only 16 bits.  Use the right type of
__raw_read when accessing it.

Problem found by Yaroslav Vinogradov <yaroslav.vinogradov@freescale.com>

Subject: [PATCH] m68knommu: switch 68360 to using rtc_time

Adds support for RTCs (through genrtc) for M68KNOMMU.

Board-specific code will have to link the appropriate RTC driver to the
mach_hwclk callback, at minimum.

This patch switches the 68360 code over to using rtc_time.

Subject: [MIPS] Compile __do_IRQ() when really needed

__do_IRQ() is needed only by irq handlers that can't use
default handlers defined in kernel/irq/chip.c.

For others platforms there's no need to compile this function
since it won't be used. For those platforms this patch defines
GENERIC_HARDIRQS_NO__DO_IRQ symbol which is used exactly for
this purpose.

Futhermore for platforms which do not use __do_IRQ(), end()
method which is part of the 'irq_chip' structure is not used.
This patch simply removes this method in this case.

Subject: [IA64] Fix pci.c kernel compilation breakage.

The recent change to convert the is_enabled flag in the PCI device to an
atomic count broke the IA64 compilation.

As pcibios_disable_device is only ever called if the reference count
is zero, convert the if to a BUG_ON.

Subject: [PATCH] i386: fix buggy MTRR address checks

Fix checks that failed to realize that values are 4-kB-unit-sized (note the
format strings in this same diff context which *do* realize the unit size,
via appended "000"!).  Also fix an incorrect below-1MB area check (as
gathered from Jan Beulich's unapplied patch at
http://www.ussg.iu.edu/hypermail/linux/kernel/0411.1/1378.html ) Update
mtrr_add_page() docu to make 4-kB-sized calculation more obvious.

Given several further items mentioned in Jan's patch mail, all in all MTRR
code seems surprisingly buggy, for a surprisingly long period of time (many
years).  Further work/investigation would be useful.

TBD Note that my patch is pretty much UNTESTED, since I can only verify that it
TBD successfully boots my machine, but I cannot test against actual buggy
TBD hardware which would require these (formerly broken) checks.  Long -mm
TBD simmering would make sense, especially since these now-working checks might
TBD turn out to have adverse effects on unaffected hardware.

Subject: [PATCH] x86: Compress stack unwinder output

The unwinder has some extra newlines, which eat up loads of screen
space when it spews. (See https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=137900
for a nasty example).

warning_symbol-> and warning-> already printk a newline, so don't add one
in the strings passed to them.

[AK: redone for new code]

Subject: [PATCH] i386: remove default_ldt, and simplify ldt-setting.

This patch removes the default_ldt[] array, as it has been unused since
iBCS stopped being supported.  This means it is now possible to actually
set an empty LDT segment.

In order to deal with this, the set_ldt_desc/load_LDT pair has been
replaced with a single set_ldt() operation which is responsible for both
setting up the LDT descriptor in the GDT, and reloading the LDT register.
If there are no LDT entries, the LDT register is loaded with a NULL
descriptor.

Subject: [PATCH] x86: all cpu backtrace

When a spinlock lockup occurs, arrange for the NMI code to emit an all-cpu
backtrace, so we get to see which CPU is holding the lock, and where.

Subject: [PATCH] i386: espfix cleanup

Clean up the espfix code:

- Introduced PER_CPU() macro to be used from asm
- Introduced GET_DESC_BASE() macro to be used from asm
- Rewrote the fixup code in asm, as calling a C code with the altered %ss
  appeared to be unsafe
- No longer altering the stack from a .fixup section
- 16bit per-cpu stack is no longer used, instead the stack segment base
  is patched the way so that the high word of the kernel and user %esp
  are the same.
- Added the limit-patching for the espfix segment. (Chuck Ebbert)

Subject: [PATCH] i386: add sleazy FPU optimization

i386 port of the sLeAZY-fpu feature.  Chuck reports that this gives him a +/-
0.4% improvement on his simple benchmark

x86_64 description follows:

Right now the kernel on x86-64 has a 100% lazy fpu behavior: after *every*
context switch a trap is taken for the first FPU use to restore the FPU
context lazily.  This is of course great for applications that have very
sporadic or no FPU use (since then you avoid doing the expensive save/restore
all the time).  However for very frequent FPU users...  you take an extra trap
every context switch.

The patch below adds a simple heuristic to this code: After 5 consecutive
context switches of FPU use, the lazy behavior is disabled and the context
gets restored every context switch.  If the app indeed uses the FPU, the trap
is avoided.  (the chance of the 6th time slice using FPU after the previous 5
having done so are quite high obviously).

After 256 switches, this is reset and lazy behavior is returned (until there
are 5 consecutive ones again).  The reason for this is to give apps that do
longer bursts of FPU use still the lazy behavior back after some time.

Subject: [PATCH] x86-64: Insert Local and IO APIC(s) into resource map

Insert the Local APIC and IO APIC(s) into the resource tree.  It allows the
APIC resources to be visible within /proc/iomem.  The patch also takes into
account IO APIC(s) mapped in the PCI space by deferring the insertion until
after PCI has allocated its necessary resources.

- makes ret_from_sys_call no longer global (all external users were
  previously switched to use int_ret_from_sys_call)
- adjusts placement of a CFI_{REMEMBER,RESTORE}_STATE pair to better
  fit logic flow
- eliminates an unnecessary pair of CFI_{REMEMBER,RESTORE}_STATE
- glues together function- and unwinder-wise the previously separate
  system_call and int_ret_from_sys_call function fragments

Subject: [PATCH] i386: Use asm-offsets for the offsets of registers into the
 pt_regs struct

Use asm-offsets for the offsets of registers into the pt_regs struct, rather
than having hard-coded constants

I left the constants in the comments of entry.S because they're useful for
reference; the code in entry.S is very dependent on the layout of pt_regs,
even when using asm-offsets.

Subject: [PATCH] i386: Basic definitions for i386-pda

This patch has the basic definitions of struct i386_pda, and the segment
selector in the GDT.

asm-i386/pda.h is more or less a direct copy of asm-x86_64/pda.h.  The most
interesting difference is the use of _proxy_pda, which is used to give gcc a
model for the actual memory operations on the real pda structure.  No actual
reference is ever made to _proxy_pda, so it is never defined.

Subject: [PATCH] i386: Initialize the per-CPU data area

When a CPU is brought up, a PDA and GDT are allocated for it.  The GDT's
__KERNEL_PDA entry is pointed to the allocated PDA memory, so that all
references using this segment descriptor will refer to the PDA.

This patch rearranges CPU initialization a bit, so that the GDT/PDA are set up
as early as possible in cpu_init().  Also for secondary CPUs, GDT+PDA are
preallocated and initialized so all the secondary CPU needs to do is set up
the ldt and load %gs.  This will be important once smp_processor_id() and
current use the PDA.

In all cases, the PDA is set up in head.S, before a CPU starts running C code,
so the PDA is always available.

From f95d47caae5302a63d92be9a0292abc90e2a14e1 Mon Sep 17 00:00:00 2001
From: Jeremy Fitzhardinge <jeremy@goop.org>
Date: Thu, 7 Dec 2006 02:14:02 +0100
Subject: [PATCH] i386: Use %gs as the PDA base-segment in the kernel

This patch is the meat of the PDA change.  This patch makes several related
changes:

1: Most significantly, %gs is now used in the kernel.  This means that on
   entry, the old value of %gs is saved away, and it is reloaded with
   __KERNEL_PDA.

2: entry.S constructs the stack in the shape of struct pt_regs, and this
   is passed around the kernel so that the process's saved register
   state can be accessed.

   Unfortunately struct pt_regs doesn't currently have space for %gs
   (or %fs). This patch extends pt_regs to add space for gs (no space
   is allocated for %fs, since it won't be used, and it would just
   complicate the code in entry.S to work around the space).

3: Because %gs is now saved on the stack like %ds, %es and the integer
   registers, there are a number of places where it no longer needs to
   be handled specially; namely context switch, and saving/restoring the
   register state in a signal context.

4: And since kernel threads run in kernel space and call normal kernel
   code, they need to be created with their %gs == __KERNEL_PDA.

Subject: [PATCH] i386: Fix places where using %gs changes the usermode ABI

There are a few places where the change in struct pt_regs and the use of %gs
affect the userspace ABI.  These are primarily debugging interfaces where
thread state can be inspected or extracted.

Subject: [PATCH] i386: Update sys_vm86 to cope with changed pt_regs and %gs
 usage

sys_vm86 uses a struct kernel_vm86_regs, which is identical to pt_regs, but
adds an extra space for all the segment registers.  Previously this structure
was completely independent, so changes in pt_regs had to be reflected in
kernel_vm86_regs.  This changes just embeds pt_regs in kernel_vm86_regs, and
makes the appropriate changes to vm86.c to deal with the new naming.

Also, since %gs is dealt with differently in the kernel, this change adjusts
vm86.c to reflect this.

While making these changes, I also cleaned up some frankly bizarre code which
was added when auditing was added to sys_vm86.

Subject: [PATCH] i386: Implement smp_processor_id() with the PDA

Use the cpu_number in the PDA to implement raw_smp_processor_id.  This is a
little simpler than using thread_info, though the cpu field in thread_info
cannot be removed since it is used for things other than getting the current
CPU in common code.

Subject: [PATCH] x86: Don't use nested idle loops

Currently the idle loop has two nested loops -- one high level
in cpu_idle and in some low level idle functions another one.

Looping in the low level idle functions breaks the idle notifiers
because interrupts waking up sleep states need to execute
exit_idle() which is only in cpu_idle().

So don't do that, only loop in cpu_idle(). This only removes
code.

In some cases e.g. poll_idle the idle loop is a little longer
now because cpu_idle checks more things. I hope that isn't a problem
ACPI idle doesn't change behaviour because it never looped anyways.

Subject: [PATCH] i386: Distinguish absolute symbols

Ld knows about 2 kinds of symbols,  absolute and section
relative.  Section relative symbols symbols change value
when a section is moved and absolute symbols do not.

Currently in the linker script we have several labels
marking the beginning and ending of sections that
are outside of sections, making them absolute symbols.
Having a mixture of absolute and section relative
symbols refereing to the same data is currently harmless
but it is confusing.

This must be done carefully as newer revs of ld do not place
symbols that appear in sections without data and instead
ld makes those symbols global :(

My ultimate goal is to build a relocatable kernel.  The
safest and least intrusive technique is to generate
relocation entries so the kernel can be relocated at load
time.  The only penalty would be an increase in the size
of the kernel binary.  The problem is that if absolute and
relocatable symbols are not properly specified absolute symbols
will be relocated or section relative symbols won't be, which
is fatal.

The practical motivation is that when generating kernels that
will run from a reserved area for analyzing what caused
a kernel panic, it is simpler if you don't need to hard code
the physical memory location they will run at, especially
for the distributions.

[AK: and merged:]

o Also put a message so that in future people can be aware of it and
  avoid introducing absolute symbols.

Subject: [PATCH] i386: Reserve kernel memory starting from _text

Currently when we are reserving the memory the kernel text
resides in we start at __PHYSICAL_START which happens to be
correct but not very obvious.  In addition when we start relocating
the kernel __PHYSICAL_START is the wrong value, as it is an
absolute symbol that does not get relocated.

By starting the reservation at __pa_symbol(_text)
the code is clearer and will be correct when relocated.

Subject: [PATCH] i386: CONFIG_PHYSICAL_START cleanup

Defining __PHYSICAL_START and __KERNEL_START in asm-i386/page.h works but
it triggers a full kernel rebuild for the silliest of reasons.  This
modifies the users to directly use CONFIG_PHYSICAL_START and linux/config.h
which prevents the full rebuild problem, which makes the code much
more maintainer and hopefully user friendly.

Subject: [PATCH] relocatable kernel: Kallsyms generate relocatable symbols

Print the addresses of non-absolute symbols relative to _text
so that ld will generate relocations.  Allowing a relocatable
kernel to relocate them.  We can't actually use the symbol names
because kallsyms includes static symbols that are not exported
from their object files.

Add the _text symbol definitions to the architectures which don't
define it otherwise linker will fail.

Subject: [PATCH] i386: Relocatable kernel support

This patch modifies the i386 kernel so that if CONFIG_RELOCATABLE is
selected it will be able to be loaded at any 4K aligned address below
1G.  The technique used is to compile the decompressor with -fPIC and
modify it so the decompressor is fully relocatable.  For the main
kernel relocations are generated.  Resulting in a kernel that is relocatable
with no runtime overhead and no need to modify the source code.

A reserved 32bit word in the parameters has been assigned
to serve as a stack so we figure out where are running.

+ * Files divided into blocks
+ * 1 bit (last block flag)
+ * 2 bits (block type)
+ *
+ * 1 block occurs every 32K -1 bytes or when there 50% compression has been achieved.
+ * The smallest block type encoding is always used.

+ *
+ *
+ * The buffer for decompression in place is the length of the
+ * uncompressed data, plus a small amount extra to keep the algorithm safe.
+ * The compressed data is placed at the end of the buffer.  The output
+ * pointer is placed at the start of the buffer and the input pointer
+ * is placed where the compressed data starts.  Problems will occur
+ * when the output pointer overruns the input pointer.
+ *
+ * The output pointer can only overrun the input pointer if the input
+ * pointer is moving faster than the output pointer.  A condition only
+ * triggered by data whose compressed form is larger than the uncompressed
+ * form.
+ *
+ * The worst case at the block level is a growth of the compressed data
+ * of 5 bytes per 32767 bytes.
+ *
+ * The worst case internal to a compressed block is very hard to figure.
+ * The worst case can at least be boundined by having one bit that represents
+ * 32764 bytes and then all of the rest of the bytes representing the very
+ * very last byte.
+ *
+ * All of which is enough to compute an amount of extra data that is required
+ * to be safe.  To avoid problems at the block level allocating 5 extra bytes
+ * per 32767 bytes of data is sufficient.  To avoind problems internal to a block
+ * adding an extra 32767 bytes (the worst case uncompressed block size) is
+ * sufficient, to ensure that in the worst case the decompressed data for
+ * block will stop the byte before the compressed data for a block begins.
+ * To avoid problems with the compressed data's meta information an extra 18
+ * bytes are needed.  Leading to the formula:
+ *
+ * extra_bytes = (uncompressed_size >> 12) + 32768 + 18 + decompressor_size.
+ *
+ * Adding 8 bytes per 32K is a bit excessive but much easier to calculate.
+ * Adding 32768 instead of 32767 just makes for round numbers.
+ * Adding the decompressor_size is necessary as it musht live after all
+ * of the data as well.  Last I measured the decompressor is about 14K.
+ * 10K of actuall data and 4K of bss.

Subject: [PATCH] i386: Warn upon absolute relocations being present

o Relocations generated w.r.t absolute symbols are not processed as by
  definition, absolute symbols are not to be relocated. Explicitly warn
  user about absolutions relocations present at compile time.

o These relocations get introduced either due to linker optimizations or
  some programming oversights.

o Also create a list of symbols which have been audited to be safe and
  don't emit warnings for these.

Subject: [PATCH] i386: Implement CONFIG_PHYSICAL_ALIGN

o Now CONFIG_PHYSICAL_START is being replaced with CONFIG_PHYSICAL_ALIGN.
  Hardcoding the kernel physical start value creates a problem in relocatable
  kernel context due to boot loader limitations. For ex, if somebody
  compiles a relocatable kernel to be run from address 4MB, but this kernel
  will run from location 1MB as grub loads the kernel at physical address
  1MB. Kernel thinks that I am a relocatable kernel and I should run from
  the address I have been loaded at. So somebody wanting to run kernel
  from 4MB alignment location (for improved performance regions) can't do
  that.

o Hence, Eric proposed that probably CONFIG_PHYSICAL_ALIGN will make
  more sense in relocatable kernel context. At run time kernel will move
  itself to a physical addr location which meets user specified alignment
  restrictions.

-	  0x1000000 (16MB). This can also be set based on the "X" value as

Subject: [PATCH] i386: extend bzImage protocol for relocatable protected mode
 kernel

Extend bzImage protocol to enable bootloaders to load a completely relocatable
bzImage.  Now protected mode component of kernel is also relocatable and a
boot-loader can load the protected mode component at a differnt physical
address than 1MB.  (If kernel was built with CONFIG_RELOCATABLE)

Kexec can make use of it to load this kernel at a different physical address
to capture kernel crash dumps.

CLFLUSH is a lot faster than WBINVD so avoid the later if at all
possible.

Always pass the complete list of pages to other CPUs to cut down
the number of IPIs.

Minor other cleanup and sync with i386 version.

Subject: [PATCH] x86-64: Extend clear_irq_vector

Clear the irq releated entries in irq_vector, irq_domain and vector_irq
instead of clearing irq_vector only. So when new irq is created, it
could reuse that vector. (actually is the second loop scanning from
FIRST_DEVICE_VECTOR+8). This could avoid the vectors are used up
with enough module inserting and removing

not user addresses.

Subject: [PATCH] x86-64: Try multiple timer variants in check_timer

Instead of adding all kinds of more quirks try various timer
routing variants in check_timer.

In particular this tries to handle quirks from:
- Nvidia NF2-4 reference BIOS: wrong timer override
- Asus: Wrong timer override but no HPET table
- ATI: require timer disabled in 8259
- Some boards: require timer enabled in 8259

We just try many of the the known variants in the hopefully right order
in check_timer.

Trying pin 0/2 on Nvidia suggested by Tim Hockin.

TBD Experimental. Needs a lot of testing

Subject: [PATCH] x86-64: Support -mregparm arguments for signals with
 SA_SIGINFO in compat mode

The recent change to make x86_64 support i386 binaries compiled
with -mregparm=3 only covered signal handlers without SA_SIGINFO.
(the 3-arg "real-time" ones)

To be compatible with i386, both types should be supported.

Subject: [PATCH] Calgary: use BIOS supplied BBARs and topology information

Find the BBAR register address of each Calgary using the "Extended
BIOS Data Area" rather than calculating it ourselves. Also get the bus
topology (what PHB each bus is on) from Calgary rather than
calculating it ourselves.

This patch fixes http://bugzilla.kernel.org/show_bug.cgi?id=7407.

This patch cleans up the previous "Use BIOS supplied BBAR information"
patch. Mostly stylistic clenaups, but also check for ioremap failure
when we ioremap the BBAR rather than when trying to use it.

Subject: [PATCH] x86-64: Make x86_64 udelay() round up instead of down.

Port two patches from i386 to x86_64 delay.c to make sure all rounding is done
upward instead of downward.

There is no sign in commit messages that the mismatch was done on purpose, and
"delay() guarantees sleeping at least for the specified time" is still a valid
rule IMHO.

The original x86 patches are both from pre-GIT era, i.e.:

"[PATCH] round up  in __udelay()" in commit
54c7e1f5cc6771ff644d7bc21a2b829308bd126f

"[PATCH] add 1 in __const_udelay()" in commit
42c77a9801b8877d8b90f65f75db758822a0bccc

(both commits are from converted BK repository to x86_64).

AK: fixed gcc warning

linux/arch/x86_64/lib/delay.c:43: warning: suggest parentheses around + or - inside shift
(did this actually work?)

Subject: [PATCH] paravirt: header and stubs for paravirtualisation

Create a paravirt.h header for all the critical operations which need to be
replaced with hypervisor calls, and include that instead of defining native
operations, when CONFIG_PARAVIRT.

This patch does the dumbest possible replacement of paravirtualized
instructions: calls through a "paravirt_ops" structure.  Currently these are
function implementations of native hardware: hypervisors will override the ops
structure with their own variants.

All the pv-ops functions are declared "fastcall" so that a specific
register-based ABI is used, to make inlining assember easier.

And:

+From: Andy Whitcroft <apw@shadowen.org>

The paravirt ops introduce a 'weak' attribute onto memory_setup().
Code ordering leads to the following warnings on x86:

    arch/i386/kernel/setup.c:651: warning: weak declaration of
                `memory_setup' after first use results in unspecified behavior

Move memory_setup() to avoid this.

+	  Paravirtualization is a way of running multiple instances of
+	  Linux on the same machine, under a hypervisor.  This option
+	  changes the kernel so it can modify itself when it is run
+	  under a hypervisor, improving performance significantly.
+	  However, when run without a hypervisor the kernel is
+	  theoretically slower.  If in doubt, say N.

From 139ec7c416248b9ea227d21839235344edfee1e0 Mon Sep 17 00:00:00 2001

Subject: [PATCH] paravirt: Patch inline replacements for paravirt intercepts

It turns out that the most called ops, by several orders of magnitude,
are the interrupt manipulation ops.  These are obvious candidates for
patching, so mark them up and create infrastructure for it.

The method used is that the ops structure has a patch function, which
is called for each place which needs to be patched: this returns a
number of instructions (the rest are NOP-padded).

Usually we can spare a register (%eax) for the binary patched code to
use, but in a couple of critical places in entry.S we can't: we make
the clobbers explicit at the call site, and manually clobber the
allowed registers in debug mode as an extra check.

And:

Don't abuse CONFIG_DEBUG_KERNEL, add CONFIG_DEBUG_PARAVIRT.

And:

AK:  Fix warnings in x86-64 alternative.c build

And:

AK: Fix compilation with defconfig

And:

^From: Andrew Morton <akpm@osdl.org>

Some binutlises still like to emit references to __stop_parainstructions and
__start_parainstructions.

And:

AK: Fix warnings about unused variables when PARAVIRT is disabled.

Subject: [PATCH] paravirt: Add startup infrastructure for paravirtualization

1) Each hypervisor writes a probe function to detect whether we are
   running under that hypervisor.  paravirt_probe() registers this
   function.

2) If vmlinux is booted with ring != 0, we call all the probe
   functions (with registers except %esp intact) in link order: the
   winner will not return.

Subject: [PATCH] paravirt: Allow selected bug checks to be

Allow selected bug checks to be skipped by paravirt kernels.  The two most
important are the F00F workaround (which is either done by the hypervisor,
or not required), and the 'hlt' instruction check, which can break under
some hypervisors.

Subject: [PATCH] paravirt: Allow disable power management under hypervisor

Two legacy power management modes are much easier to just explicitly disable
when running in paravirtualized mode - neither APM nor PnP is still relevant.
The status of ACPI is still debatable, and noacpi is still a common enough
boot parameter that it is not necessary to explicitly disable ACPI.

Add APIC accessors to paravirt-ops.  Unfortunately, we need two write

Pentium APIC errata - this is the purpose of apic_write_atomic.

Subject: [PATCH] paravirt: Add MMU virtualization to paravirt_ops

Add the three bare TLB accessor functions to paravirt-ops.  Most amusingly,
flush_tlb is redefined on SMP, so I can't call the paravirt op flush_tlb.
Instead, I chose to indicate the actual flush type, kernel (global) vs. user
(non-global).  Global in this sense means using the global bit in the page
table entry, which makes TLB entries persistent across CR3 reloads, not
global as in the SMP sense of invoking remote shootdowns, so the term is
confusingly overloaded.

Subject: [PATCH] paravirt: Add option to allow skipping the timer check

Add a way to disable the timer IRQ routing check via a boot option.  The
VMI timer code uses this to avoid triggering the pester Mingo code, which
probes for some very unusual and broken motherboard routings.  It fires
100% of the time when using a paravirtual delay mechanism instead of using
a realtime delay, since there is no elapsed real time, and the 4 timer IRQs
have not yet been delivered.

In addition, it is entirely possible, though improbable, that this bug
could surface on real hardware which picks a particularly bad time to enter
SMM mode, causing a long latency during one of the timer IRQs.

While here, make check_timer be __init.

Subject: [PATCH] x86-64: Add option to compile for Core2

Add an option to compile for Intel's Core 2

The Kconfig help is a mouthful due to the inventiveness of Intel's
product naming department.

Mainly for the 64bit cache line sizes because gcc doesn't support
optimizing for core2 yet. However it will and then the kernel
should be ready by passing the right option

Also fix the old MPSC help text to confirm better to reality.

Subject: [PATCH] x86-64: fix perms/range of vsyscall vma in /proc/*/maps

The final line of /proc/<pid>/maps on x86_64 for native 64-bit
tasks shows an incorrect ending address and incorrect permissions.  There
is only a single page mapped in this vsyscall region, and it is accessible
for both read and execute.

The patch below fixes this.  (Since 32-bit-compat tasks have a real vma
with correct perms/range, no change is necessary for that scenario.)

Before the patch, a "cat /proc/self/maps | tail -1" shows this:

        ffffffffff600000-ffffffffffe00000 ---p 00000000 [...]

After the patch, this is the output:

        ffffffffff600000-ffffffffff601000 r-xp 00000000 [...]

Subject: [PATCH] i386: clear_fixmap() should not use set_pte()

While not strictly required with the current code (as the upper half of
page table entries generated by __set_fixmap() cannot be non-zero due
to the second parameter of this function being 'unsigned long'), the
use of set_pte() in __set_fixmap() in the context of clear_fixmap() is
still improper with CONFIG_X86_PAE (see the respective comment in
include/asm-i386/pgtable-3level.h) and would turn into a bug if that
second parameter ever gets changed to a 64-bit type.

Subject: [PATCH] i386: fix MTRR code

Until not so long ago, there were system log messages pointing to
inconsistent MTRR setup of the video frame buffer caused by the way vesafb
and X worked. While vesafb was fixed meanwhile, I believe fixing it there
only hides a shortcoming in the MTRR code itself, in that that code is not
symmetric with respect to the ordering of attempts to set up two (or more)
regions where one contains the other. In the current shape, it permits
only setting up sub-regions of pre-exisiting ones. The patch below makes
this symmetric.

While working on that I noticed a few more inconsistencies in that code,
namely
- use of 'unsigned int' for sizes in many, but not all places (the patch
  is converting this to use 'unsigned long' everywhere, which specifically
  might be necessary for x86-64 once a processor supporting more than 44
  physical address bits would become available)
- the code to correct inconsistent settings during secondary processor
  startup tried (if necessary) to correct, among other things, the value
  in IA32_MTRR_DEF_TYPE, however the newly computed value would never get
  used (i.e. stored in the respective MSR)
- the generic range validation code checked that the end of the
  to-be-added range would be above 1MB; the value checked should have been
  the start of the range
- when contained regions are detected, previously this was allowed only
  when the old region was uncacheable; this can be symmetric (i.e. the new
  region can also be uncacheable) and even further as per Intel's
  documentation write-trough and write-back for either region is also
  compatible with the respective opposite in the other

Subject: [PATCH] x86: add write_pci_config_byte() to direct PCI access
 routines

Mechanism of selecting physical mode in genapic when cpu hotplug is enabled on
x86_64, broke the quirk(quirk_intel_irqbalance()) introduced for working
around the transposing interrupt message errata in E7520/E7320/E7525 (revision
ID 0x9 and below.  errata #23 in
http://download.intel.com/design/chipsets/specupdt/30304203.pdf).

This errata requires the mode to be in logical flat, so that interrupts can be
directed to more than one cpu(and thus use hardware IRQ balancing enabled by
BIOS on these platforms).

Following four patches fixes this by moving the quirk to early quirk and
forcing the x86_64 genapic selection to logical flat on these platforms.

Thanks to Shaohua for pointing out the breakage.

This patch:

Add write_pci_config_byte() to direct PCI access  routines

Subject: [PATCH] x86: fix the irqbalance quirk for E7320/E7520/E7525

Move the irqbalance quirks for E7320/E7520/E7525(Errata 23 in
http://download.intel.com/design/chipsets/specupdt/30304203.pdf) to early
quirks.

And add a PCI quirk for these platforms to check(which happens very late
during the boot) if the APIC routing is indeed set to default flat mode.

This fixes the breakage(in x86_64) of this quirk due to cpu hotplug which
selects physical mode instead of the logical flat(as needed for this errata
workaround).

Subject: [PATCH] i386: call efi_get_time during suspend

Function efi_get_time called not only during init kernel phase but also
during suspend (from get_cmos_time).

When it is called from get_cmos_time the corresponding runtime service
should be called in virtual and not in physical mode.

This is done like everywhere else in i386/kernel/apic.c,
so I guess its correct.
Suspends/Resumes to disk fine and eleminates an smp_error_interrupt()
here on a K8.

Subject: [PATCH] x86-64: Synchronize RDTSC on single core AMD

There is no guarantee that two RDTSCs in a row are monotonic,
so don't assume it on single core AMD systems.
This will make gettimeofday slower again

Subject: [PATCH] x86-64: Mark rdtsc as sync only for netburst, not for core2

On the Core2 cpus, the rdtsc instruction is not serializing (as defined
in the architecture reference since rdtsc exists) and due to the deep
speculation of these cores, it's possible that you can observe time go
backwards between cores due to this speculation. Since the kernel
already deals with this with the SYNC_RDTSC flag, the solution is
simple, only assume that the instruction is serializing on family 15...

The price one pays for this is a slightly slower gettimeofday (by a
dozen or two cycles), but that increase is quite small to pay for a
really-going-forward tsc counter.

Subject: [PATCH] unwinder: always use unlocked module list access in unwinder
 fallback

We're already well protected against module unloads because module
unload uses stop_machine(). The only exception is NMIs, but other
users already risk lockless accesses here.

This avoids some hackery in lockdep and also a potential deadlock

This matches what i386 does.

Subject: [PATCH] x86-64: Fix interrupt race in idle callback (3rd try)

Idle callbacks has some races when enter_idle() sets isidle and subsequent
interrupts that can happen on that CPU, before CPU goes to idle. Due to this,
an IDLE_END can get called before IDLE_START. To avoid these races, disable
interrupts before enter_idle and make sure that all idle routines do not
enable interrupts before entering idle.

Note that poll_idle() still has a this race as it has to enable interrupts
before going to idle. But, all other idle routines have the race fixed.

Subject: [PATCH] x86-64: check vector in setup_ioapic_dest to verify if need
 setup_IO_APIC_irq

setup_IO_APIC_irqs could fail to get vector for some device when you have too
many devices, because at that time only boot cpu is online.  So check vector
for irq in setup_ioapic_dest and call setup_IO_APIC_irq to make sure IO-APIC
irq-routing table is initialized.

Also seperate setup_IO_APIC_irq from setup_IO_APIC_irqs.

These handlers run with irqs disabled and do not call functions which need
"struct pt_regs".

Subject: [PATCH] i386: Clean up smp_tune_scheduling()

- remove the write-only local variable "bandwidth"
- don't set "max_cache_size" in the (cachesize < 0) case:
  that's already handled in kernel/sched.c:measure_migration_cost()

Subject: [ARM] 3982/2: Explicitly select 32-bit ARM ISA (-marm)

Do not assume that the ARM GCC toolchain defaults to building for the
32-bit ARM ISA (-marm) case. Instead, explicitly select -marm in CFLAGS
since the toolchain default can be for the 16-bit Thumb ISA (-mthumb) in
some odd/rare cases.

Subject: [PATCH] shared page table for hugetlb page

Following up with the work on shared page table done by Dave McCracken.  This
set of patch target shared page table for hugetlb memory only.

The shared page table is particular useful in the situation of large number of
independent processes sharing large shared memory segments.  In the normal
page case, the amount of memory saved from process' page table is quite
significant.  For hugetlb, the saving on page table memory is not the primary
objective (as hugetlb itself already cuts down page table overhead
significantly), instead, the purpose of using shared page table on hugetlb is
to allow faster TLB refill and smaller cache pollution upon TLB miss.

With PT sharing, pte entries are shared among hundreds of processes, the cache
consumption used by all the page table is smaller and in return, application
gets much higher cache hit ratio.  One other effect is that cache hit ratio
with hardware page walker hitting on pte in cache will be higher and this
helps to reduce tlb miss latency.  These two effects contribute to higher
application performance.

Subject: [PATCH] mm: arch do_page_fault() vs in_atomic()

In light of the recent pagefault and filemap_copy_from_user work I've gone
through all the arch pagefault handlers to make sure the inc_preempt_count()
'feature' works as expected.

Several sections of code (including the new filemap_copy_from_user) rely on
the fact that faults do not take locks under increased preempt count.

Subject: [PATCH] mm: pagefault_{disable,enable}()

Introduce pagefault_{disable,enable}() and use these where previously we did
manual preempt increments/decrements to make the pagefault handler do the
atomic thing.

Currently they still rely on the increased preempt count, but do not rely on
the disabled preemption, this might go away in the future.

(NOTE: the extra barrier() in pagefault_disable might fix some holes on
       machines which have too many registers for their own good)

Subject: [PATCH] Fix kunmap_atomic's use of kpte_clear_flush()

kunmap_atomic() will call kpte_clear_flush with vaddr/ptep arguments which
don't correspond if the vaddr is just a normal lowmem address (ie, not in
the KMAP area).  This patch makes sure that the pte is only cleared if kmap
area was actually used for the mapping.

Subject: [PATCH] Allow NULL pointers in percpu_free

The patch (as824b) makes percpu_free() ignore NULL arguments, as one would
expect for a deallocation routine.  (Note that free_percpu is #defined as
percpu_free in include/linux/percpu.h.) A few callers are updated to remove
now-unneeded tests for NULL.  A few other callers already seem to assume
that passing a NULL pointer to percpu_free() is okay!

The patch also removes an unnecessary NULL check in percpu_depopulate().

Subject: [PATCH] slab: remove kmem_cache_t

Replace all uses of kmem_cache_t with struct kmem_cache.

The patch was generated using the following script:

	#!/bin/sh
	#
	# Replace one string by another in all the kernel sources.
	#

	set -e

	for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do
		quilt add $file
		sed -e "1,\$s/$1/$2/g" $file >/tmp/$$
		mv /tmp/$$ $file
		quilt refresh
	done

The script was run like this

	sh replace kmem_cache_t "struct kmem_cache"

Subject: [PATCH] avr32: fixup kprobes preemption handling

While working on SH kprobes, I noticed that avr32 got the preemption
handling wrong in the no probe case.  The idea is that upon entry of
kprobe_handler() preemption is disabled outright across the life of the
kprobe, only to be re-enabled in post_kprobe_handler().

However, in the event that the probe is never activated, there's never any
chance of hitting the post probe handler, which allows for the current
avr32 implementation to disable preemption indefinitely, as it's currently
missing a re-enable when no probe is activated.

Subject: [PATCH] alpha: switch to pci_get API

Now that we have pci_get_bus_and_slot we can do the job correctly.  Note that
some of these calls intentionally leak a device - this is because the device
in question is always needed from boot to reboot.

Subject: [PATCH] swsusp: Support i386 systems with PAE or without PSE

Make swsusp support i386 systems with PAE or without PSE.

This is done by creating temporary page tables located in resume-safe page
frames before the suspend image is restored in the same way as x86_64 does
it.

Subject: [PATCH] uml: use get_random_bytes() after random pool is seeded

When the UML network driver generates random MACs for its devices, it was
possible for a number of UMLs to get the same MACs because the ethernet
initialization was done before the random pool was properly seeded.

This patch moves the initialization later so that it gets better randomness.

Subject: [PATCH] remove kernel syscalls

The last thing we agreed on was to remove the macros entirely for 2.6.19,
on all architectures. Unfortunately, I think nobody actually _did_ that,
so they are still there.

Define elf_addr_t in linux/elf.h.  The size of the type is determined using
ELF_CLASS.  This allows us to remove the defines that today are spread all
over .c and .h files.

Subject: [PATCH] kprobes: enable booster on the preemptible kernel

When we are unregistering a kprobe-booster, we can't release its
instruction buffer immediately on the preemptive kernel, because some
processes might be preempted on the buffer.  The freeze_processes() and
thaw_processes() functions can clean most of processes up from the buffer.
There are still some non-frozen threads who have the PF_NOFREEZE flag.  If
those threads are sleeping (not preempted) at the known place outside the
buffer, we can ensure safety of freeing.

However, the processing of this check routine takes a long time.  So, this
patch introduces the garbage collection mechanism of insn_slot.  It also
introduces the "dirty" flag to free_insn_slot because of efficiency.

The "clean" instruction slots (dirty flag is cleared) are released
immediately.  But the "dirty" slots which are used by boosted kprobes, are
marked as garbages.  collect_garbage_slots() will be invoked to release
"dirty" slots if there are more than INSNS_PER_PAGE garbage slots or if
there are no unused slots.

Subject: [PATCH] smp_call_function_single() check that local interrupts are
 enabled

smp_call_function_single() can deadlock if the caller disabled local
interrupts (the target CPU could be spinning on call_lock).  Check for that.

Why on earth do these functions use spin_lock_bh()??

Subject: [PATCH] hotplug CPU: clean up hotcpu_notifier() use

There was lots of #ifdef noise in the kernel due to hotcpu_notifier(fn,
prio) not correctly marking 'fn' as used in the !HOTPLUG_CPU case, and thus
generating compiler warnings of unused symbols, hence forcing people to add
#ifdefs.

the compiler can skip truly unused functions just fine:

    text    data     bss     dec     hex filename

Subject: [PATCH] add rtc-omap driver

This creates a new RTC-framework driver for the RTC/calendar module found
in various OMAP1 chips.  (OMAP2 and OMAP3 use external RTCs, like those in
TI's multifunction PM companion chips.) It's been in the Linux-OMAP tree
for several months now, and other trees before that, so it's quite stable.
The most notable issue is that the OMAP IRQ code doesn't yet support the
RTC IRQ as a wakeup event.  Once that's fixed, a patch will be needed.

Subject: [PATCH] Kexec / Kdump: Unify elf note code

The elf note saving code is currently duplicated over several
architectures.  This cleanup patch simply adds code to a common file and
then replaces the arch-specific code with calls to the newly added code.

The only drawback with this approach is that s390 doesn't fully support
kexec-on-panic which for that arch leads to introduction of unused code.

From 285f5fa7e9a35e75d9022f9b036ed709721c5cdf Mon Sep 17 00:00:00 2001
From: Dan Williams <dan.j.williams@intel.com>
Date: Thu, 7 Dec 2006 02:59:39 +0100
Subject: [ARM] 3995/1: iop13xx: add iop13xx support

The iop348 processor integrates an Xscale (XSC3 512KB L2 Cache) core with a
Serial Attached SCSI (SAS) controller, multi-ported DDR2 memory
controller, 3 Application Direct Memory Access (DMA) controllers, a 133Mhz
PCI-X interface, a x8 PCI-Express interface, and other peripherals to form
a system-on-a-chip RAID subsystem engine.

The iop342 processor replaces the SAS controller with a second Xscale core
for dual core embedded applications.

The iop341 processor is the single core version of iop342.

This patch supports the two Intel customer reference platforms iq81340mc
for external storage and iq81340sc for direct attach (HBA) development.

The developer's manual is available here:
ftp://download.intel.com/design/iio/docs/31503701.pdf

Changelog:
* removed virtual addresses from resource definitions
* cleaned up some unnecessary #include's

Subject: [IA64] SN: Correctly update smp_affinty mask

On Altix systems, the /proc/irq/nn/smp_affinity mask is not being setup
at device iniitalization, or updated after an interrupt redirection.
This patch resolves those issues.

Subject: [IA64] Update processor_info features

Add the printing of additional processor features to proc_features.

Based on Rev 2.2 of Volume 2 of "Intel Itanium Architecture Software
Developer's Manual" (January 2006) fields (pages 2:430-2:432).
This patch gets the features back in sync with the spec.

Subject: [IA64] tidy up return value of ip_fast_csum

While working on implementing csum_ipv6_magic, I noticed that current
version of ip_fast_csum will potentially return bits above "unsigned
short" as 1.  While no harm is done right now because all call sites
will chop off the upper bits when it uses the return value.  However,
this is still dangerous and buggy.  Here is a patch to enforce that the
function really returns unsigned short in the native register format.

The fix is free as there are plenty open slot to add one more asm instruction.

Subject: [PATCH] Add support for type argument in PAL_GET_PSTATE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PAL_GET_PSTATE accepts a type argument to return different kinds of
frequency information.
Refer: Intel Itanium®Architecture Software Developer's Manual -
Volume 2: System Architecture, Revision 2.2
(http://developer.intel.com/design/itanium/manuals/245318.htm)

Add the support for type argument and use Instantaneous frequency
in the acpi driver.

Also fix a bug, where in return value of PAL_GET_PSTATE was getting compared
with 'control' bits instead of 'status' bits.

Subject: [ARM] 3983/2: remove unused argument to __bug()

It appears that include/asm-arm/bug.h requires include/linux/stddef.h
for the definition of NULL. It seems that stddef.h was always included
indirectly in most cases, and that issue was properly fixed a while ago.

Then commit 5047f09b56d0bc3c21aec9cb16de60283da645c6 incorrectly reverted
change from commit ff10952a547dad934d9ed9afc5cf579ed1ccb53a (bad dwmw2)
and the problem recently resurfaced.

Because the third argument to __bug() is never used anyway, RMK suggested
getting rid of it entirely instead of readding #include <linux/stddef.h>
which this patch does.

Subject: [ARM] 4002/1: S3C24XX: leave parent IRQs unmasked

Do not bother masking/unmasking the parent IRQ
for the mulitplexed EINT irqs, as masking the
leaf seems to be fine.

As the first step in consolidating the pseries hotplug cpu code,
create platforms/pseries/hotplug-cpu.c and move rtas_stop_self()
into it.  Do the rtas token initialisation in a new initcall, rather
than rtas_initialize().

Subject: [POWERPC] Move pSeries_mach_cpu_die() into
 platforms/pseries/hotplug-cpu.c

Move pSeries_mach_cpu_die() into platforms/pseries/hotplug-cpu.c,
this allows rtas_stop_self() to be static so remove the prototype.

Wire up pSeries_mach_cpu_die() in the initcall, rather than statically
in setup.c, the initcall will still run prior to the cpu hotplug code
being callable, so there should be no change in behaviour.

Subject: [POWERPC] Only enable cpu hotplug via RTAS if the required firmware
 support is found

To support cpu hotplug on pseries we require two RTAS tokens.  The cpu
hotplug machinery should only be wired up if these tokens are found in
the device tree.

If one attempts to create a device driver recovery sequence that
does not depend on a hard reset of the device, but simply just
attempts to resume processing, then one discovers that the
recovery sequence implemented on powerpc is not quite right.
This patch fixes this up.

Subject: [POWERPC] qe_ic: Do a sync when masking interrupts

This patch causes a sync do be done after masking a QE interrupt, to
ensure that the masking has completed before interrupts are enabled.
This allows the masking of the cascade IRQ to be removed without causing
spurious interrupts.

The mask_and_ack function is also removed and set to the mask function,
as the two are identical.

Subject: [POWERPC] maple: Match "pcie" name for CPC945

Some firmwares have "pcie" for the "name" property of the CPC945 PCI
Express host bridge.  Check for "pcie" in addition to "pci" so we
don't miss it.

Subject: [POWERPC] Add rtas_service_present() helper

To test for the existence of an RTAS function, we typically do:

   foo_token = rtas_token("foo");
   if (foo_token == RTAS_UNKNOWN_SERVICE)
      return;

Add a rtas_service_present method, which provides a more conventional
boolean interface for testing the existence of an RTAS method.

Subject: [POWERPC] Fix mmap of PCI resource with hack for X

The powerpc version of pci_resource_to_user() and associated hooks
used by /proc/bus/pci and /sys/bus/pci mmap have been broken for some
time on machines that don't have a 1:1 mapping of devices (basically
on non-PowerMacs) and have PCI devices above 32 bits.

This attempts to fix it as well as possible.

The rule is supposed to be that pci_resource_to_user() always converts
the resources back into a BAR values since that's what the /proc
interface was supposed to deal with. However, for X to work on
platforms where PCI MMIO is not mapped 1:1, it became a habit of
platforms like powerpc to pass "fixed up" values there since X expects
to be able to use values from /proc/bus/pci/devices as offsets to mmap
of /dev/mem...

So we keep that contraption here, causing also /sys/*/resource to
expose fully absolute MMIO addresses instead of BAR values, which is
ugly, but should still work as long as those are only used to calculate
alignment within a page.

X is still broken when built 32 bits on machines where PCI MMIO can be
above 32-bit space unfortunately.

Subject: [POWERPC] Add support for FP emulation for the e300c2 core

The e300c2 has no FPU.  Its MSR[FP] is grounded to zero.  If an attempt
is made to execute a floating point instruction (including floating-point
load, store, or move instructions), the e300c2 takes a floating-point
unavailable interrupt.

This patch adds support for FP emulation on the e300c2 by declaring a
new CPU_FTR_FP_TAKES_FPUNAVAIL, where FP unavail interrupts are
intercepted and redirected to the ProgramCheck exception path for
correct emulation handling.

(If we run out of CPU_FTR bits we could look to reclaim this bit by adding
support to test the cpu_user_features for PPC_FEATURE_HAS_FPU instead)

It adds a nop to the exception path for 32-bit processors with a FPU.

Subject: [AVR32] Move ethernet tag parsing to board-specific code

By moving the ethernet tag parsing to the board-specific code we avoid
the issue of figuring out which device we're supposed to attach the
information to.  The board specific code knows this because it's
where the actual devices are instantiated.

Subject: [AVR32] Remove mii_phy_addr and eth_addr from eth_platform_data

The macb driver will probe for the PHY chip and read the mac address
from the MACB registers, so we don't need them in eth_platform_data
anymore.

Since u-boot doesn't currently initialize the MACB registers with the
mac addresses, the tag parsing code is kept but instead of sticking
the information into eth_platform_data, it uses it to initialize
the MACB registers (in case the boot loader didn't do it.) This code
should be unnecessary at some point in the future.

Subject: [AVR32] Put the chip in "stop" mode when halting the system

Make machine_halt() execute a sleep instruction to put the chip in
"stop" mode when the system is halted. This switches off all clocks
except the 32 kHz oscillator, which is needed for the RTC to keep
ticking.

Subject: [S390] Virtual memmap for s390.

Virtual memmap support for s390. Inspired by the ia64 implementation.

Unlike ia64 we need a mechanism which allows us to dynamically attach
shared memory regions.
These memory regions are accessed via the dcss device driver. dcss
implements the 'direct_access' operation, which requires struct pages
for every single shared page.
Therefore this implementation provides an interface to attach/detach
shared memory:

int add_shared_memory(unsigned long start, unsigned long size);
int remove_shared_memory(unsigned long start, unsigned long size);

The purpose of the add_shared_memory function is to add the given
memory range to the 1:1 mapping and to make sure that the
corresponding range in the vmemmap is backed with physical pages.
It also initialises the new struct pages.

remove_shared_memory in turn only invalidates the page table
entries in the 1:1 mapping. The page tables and the memory used for
struct pages in the vmemmap are currently not freed. They will be
reused when the next segment will be attached.
Given that the maximum size of a shared memory region is 2GB and
in addition all regions must reside below 2GB this is not too much of
a restriction, but there is room for improvement.

Subject: [PATCH] m32r: make userspace headers platform-independent

The m32r kernel 2.6.18-rc1 or after cause build errors of "unknown isa
configuration" for userspace application programs, such as glibc, gdb, etc.

This is because the recent kernel do not include linux/config.h not to expose
kernel headers for userspace.

To fix the above compile errors, this patch fixes two headers ptrace.h and
sigcontext.h for m32r and makes them platform-independent.

Subject: [PATCH] m32r: fix ace_handler to pass full 32-bit address

Don't mask the lower 12-bit of the page fault address.

In the current m32r kernel implementation, we use an access exception
to detect page faults.

This patch fixes ace_handler (access exception handler) for m32r.  In order to
check userspace address in do_page_fault, we have to pass full 32-bit address
to do_page_fault.

Subject: [PATCH] tty: ->signal->tty locking

Fix the locking of signal->tty.

Use ->sighand->siglock to protect ->signal->tty; this lock is already used
by most other members of ->signal/->sighand.  And unless we are 'current'
or the tasklist_lock is held we need ->siglock to access ->signal anyway.

(NOTE: sys_unshare() is broken wrt ->sighand locking rules)

Note that tty_mutex is held over tty destruction, so while holding
tty_mutex any tty pointer remains valid.  Otherwise the lifetime of ttys
are governed by their open file handles.  This leaves some holes for tty
access from signal->tty (or any other non file related tty access).

It solves the tty SLAB scribbles we were seeing.

(NOTE: the change from group_send_sig_info to __group_send_sig_info needs to
       be examined by someone familiar with the security framework, I think
       it is safe given the SEND_SIG_PRIV from other __group_send_sig_info
       invocations)

Subject: [PATCH] Generic BUG for i386

This makes i386 use the generic BUG machinery.  There are no functional
changes from the old i386 implementation.

The main advantage in using the generic BUG machinery for i386 is that the
inlined overhead of BUG is just the ud2a instruction; the file+line(+function)
information are no longer inlined into the instruction stream.  This reduces
cache pollution, and makes disassembly work properly.

Subject: [PATCH] UML: add generic BUG support

The BUG changes in -mm3 need some arch support.  This patch adds the UML
support needed.  For the most part, it was stolen from the underlying
architecture.  The exception is the kernel eip < PAGE_OFFSET test, which is
wrong for skas mode UMLs.

From f0d1b0b30d250a07627ad8b9fbbb5c7cc08422e8 Mon Sep 17 00:00:00 2001
From: David Howells <dhowells@redhat.com>
Date: Fri, 8 Dec 2006 02:37:49 -0800
Subject: [PATCH] LOG2: Implement a general integer log2 facility in the kernel

This facility provides three entry points:

	ilog2()		Log base 2 of unsigned long
	ilog2_u32()	Log base 2 of u32
	ilog2_u64()	Log base 2 of u64

These facilities can either be used inside functions on dynamic data:

	int do_something(long q)
	{
		...;
		y = ilog2(x)
		...;
	}

Or can be used to statically initialise global variables with constant values:

	unsigned n = ilog2(27);

When performing static initialisation, the compiler will report "error:
initializer element is not constant" if asked to take a log of zero or of
something not reducible to a constant.  They treat negative numbers as
unsigned.

When not dealing with a constant, they fall back to using fls() which permits
them to use arch-specific log calculation instructions - such as BSR on
x86/x86_64 or SCAN on FRV - if available.

Subject: [PATCH] tty: switch to ktermios

This is the grungy swap all the occurrences in the right places patch that
goes with the updates.  At this point we have the same functionality as
before (except that sgttyb() returns speeds not zero) and are ready to
begin turning new stuff on providing nobody reports lots of bugs

If you are a tty driver author converting an out of tree driver the only
impact should be termios->ktermios name changes for the speed/property
setting functions from your upper layers.

If you are implementing your own TCGETS function before then your driver
was broken already and its about to get a whole lot more painful for you so
please fix it 8)

Also fill in c_ispeed/ospeed on init for most devices, although the current
code will do this for you anyway but I'd like eventually to lose that extra
paranoia

Subject: [POWERPC] Add DSCR SPR to sysfs

POWER6 adds a new SPR, the data stream control register (DSCR). It can
be used to adjust how agressive the prefetch mechanisms are.

Its possible we may want to context switch this, but for now just export
it to userspace via sysfs so we can adjust it.

Subject: [POWERPC] dont allow pSeries_probe to succeed without initialising
 MMU

pSeries_probe can decide that we are a pseries but then fail to
initialise the MMU. If an rtas node doesnt exist, we continually fall
out of pSeries_probe_hypertas early and never get to the MMU init code.

While pseries without RTAS is an illegal combination, the way we
currently fail is a pain to track down, and can happen if your flattened
device tree code has issues (like mine did :).

With the following patch we init the MMU, come up and print some
warnings about RTAS not existing, instead of looping on 0x400 exceptions.

From 773ff78838ca3c07245e45c06235e0baaa5f710a Mon Sep 17 00:00:00 2001
From: Atsushi Nemoto <anemo@mba.ocn.ne.jp>
Date: Fri, 8 Dec 2006 01:04:45 +0900
Subject: [MIPS] Optimize flow of csum_partial

Delete dead codes at end of the function and move small_csumcopy
there.  This makes some labels (maybe_end_cruft, small_memcpy,
end_bytes, out) needless and eliminates some branches.

Subject: [PATCH] x86: Fix boot hang due to nmi watchdog init code

2.6.19  stopped booting (or booted based on build/config) on our x86_64
systems due to a bug introduced in 2.6.19.  check_nmi_watchdog schedules an
IPI on all cpus to  busy wait on a flag, but fails to set the busywait
flag if NMI functionality is disabled.  This causes the secondary cpus
to spin in an endless loop, causing the kernel bootup to hang.
Depending upon the build, the  busywait flag got overwritten (stack variable)
and caused  the kernel to bootup on certain builds.  Following patch fixes
the bug by setting the busywait flag before returning from check_nmi_watchdog.
I guess using a stack variable is not good here as the calling function could
potentially return while the busy wait loop is still spinning on the flag.

AK: I redid the patch significantly to be cleaner

Subject: [PATCH] x86: Work around gcc 4.2 over aggressive optimizer

The new PDA code uses a dummy _proxy_pda variable to describe
memory references to the PDA. It is never referenced
in inline assembly, but exists as input/output arguments.
gcc 4.2 in some cases can CSE references to this which causes
unresolved symbols.  Define it to zero to avoid this.

Subject: [PATCH] i386: export smp_num_siblings for oprofile

oprofile uses smp_num_siblings without testing for CONFIG_X86_HT.
I looked at modifying oprofile, but this way is cleaner & simpler
and I didn't see a good reason not to just export it when CONFIG_SMP.

WARNING: "smp_num_siblings" [arch/i386/oprofile/oprofile.ko] undefined!

To add this logic, put the VIS instruction check at the
vis_emul() call site instead of inside of vis_emul().

Subject: [SPARC64]: Unaligned accesses to userspace are hard errors.

Userspace is forbidden from making unaligned loads and
stores.  So if we get an unaligned trap due to a
{get,put}_user(), signal a fault and run the exception
handler.

From f0882589666440d573f657cb3a1d5f66f3caa157 Mon Sep 17 00:00:00 2001
From: "David S. Miller" <davem@sunset.davemloft.net>
Date: Sun, 10 Dec 2006 02:42:03 -0800
Subject: [SPARC64]: Fix several kprobes bugs.

- relbranch_fixup(), for non-branches, would end up setting
  regs->tnpc incorrectly, in fact it would set it equal to
  regs->tpc which would cause that instruction to execute twice

  Also, if this is not a PC-relative branch, we should just
  leave regs->tnpc as-is.  This covers cases like 'jmpl' which
  branch to absolute values.

- To be absolutely %100 safe, we need to flush the instruction
  cache for all assignments to kprobe->ainsn.insn[], including
  cases like add_aggr_kprobe()

- prev_kprobe's status field needs to be 'unsigned long' to match
  the type of the value it is saving

- jprobes were totally broken:
  = jprobe_return() can run in the stack frame of the jprobe handler,
    or in an even deeper stack frame, thus we'll be in the wrong
    register window than the one from the original probe state.

    So unwind using 'restore' instructions, if necessary, right
    before we do the jprobe_return() breakpoint trap.

  = There is no reason to save/restore the register window saved
    at %sp at jprobe trigger time.  Those registers cannot be
    modified by the jprobe handler.  Also, this code was saving
    and restoring "sizeof (struct sparc_stackf)" bytes.  Depending
    upon the caller, this could clobber unrelated stack frame
    pieces if there is only a basic 128-byte register window
    stored on the stack, without the argument save area.

    So just saving and restoring struct pt_regs is sufficient.

  = Kill the "jprobe_saved_esp", totally unused.

    Also, delete "jprobe_saved_regs_location", with the stack frame
    unwind now done explicitly by jprobe_return(), this check is
    superfluous.

Subject: [PATCH] xtensa: remove extra header files

The Xtensa port contained many header files that were never needed.  This
rather lengthy patch removes all those files.  Unfortunately, there were
many dependencies that needed to be updated, so this patch touches quite a
few source files.

Subject: [PATCH] xtensa: fix system call interface

This is a long outstanding patch to finally fix the syscall interface.  The
constants used for the system calls are those we have provided in our libc
patches.  This patch also fixes the shmbuf and stat structure, and fcntl
definitions.

From bbea9f69668a3d0cf9feba15a724cd02896f8675 Mon Sep 17 00:00:00 2001
From: Vadim Lobanov <vlobanov@speakeasy.net>
Date: Sun, 10 Dec 2006 02:21:12 -0800
Subject: [PATCH] fdtable: Make fdarray and fdsets equal in size

Currently, each fdtable supports three dynamically-sized arrays of data: the
fdarray and two fdsets.  The code allows the number of fds supported by the
fdarray (fdtable->max_fds) to differ from the number of fds supported by each
of the fdsets (fdtable->max_fdset).

In practice, it is wasteful for these two sizes to differ: whenever we hit a
limit on the smaller-capacity structure, we will reallocate the entire fdtable
and all the dynamic arrays within it, so any delta in the memory used by the
larger-capacity structure will never be touched at all.

Rather than hogging this excess, we shouldn't even allocate it in the first
place, and keep the capacities of the fdarray and the fdsets equal.  This
patch removes fdtable->max_fdset.  As an added bonus, most of the supporting
code becomes simpler.

Subject: [POWERPC] Support ibm,dynamic-reconfiguration-memory nodes

For PAPR partitions with large amounts of memory, the firmware has an
alternative, more compact representation for the information about the
memory in the partition and its NUMA associativity information.  This
adds the code to the kernel to parse this alternative representation.

The other part of this patch is telling the firmware that we can
handle the alternative representation.  There is however a subtlety
here, because the firmware will invoke a reboot if the memory
representation we request is different from the representation that
firmware is currently using.  This is because firmware can't change
the representation on the fly.  Further, some firmware versions used
on POWER5+ machines have a bug where this reboot leaves the machine
with an altered value of load-base, which will prevent any kernel
booting until it is reset to the normal value (0x4000).  Because of
this bug, we do NOT set fake_elf.rpanote.new_mem_def = 1, and thus we
do not request the new representation on POWER5+ and earlier machines.
We do request the new representation on POWER6, which uses the
ibm,client-architecture-support call.

on some 32-bit powermacs (oops).  The reason is a bit obscure.
The code to parse interrupts happens earlier now, during
pcibios_fixup() as the PCI bus is being probed.  However, the
current implementation pci_device_to_OF_node() for 32-bit
powerpc relies, on machines like PowerMac which renumber PCI buses,
on a table called pci_OF_bus_map containing a map of bus numbers
between the kernel and the firmware which is setup only later.
Thus, it fails to match the device node.  In addition, some of
Apple internal PCI devices lack a proper PCI_INTERRUPT_PIN, thus
preventing the fallback mapping code to work.

This patch fixes it by making pci_device_to_OF_node() 32-bit
implementation use a different algorithm that works without
using the pci_OF_bus_map thing (which I intend to deprecate
anyway). It's a bit slower but that function isn't called in
any hot path hopefully.

Commit bbea9f69668a3d0cf9feba15a724cd02896f8675 removed the max_fdset
element of struct fdtable.  It appears that checking max_fds is

Subject: [POWERPC] Only export __mtdcr/__mfdcr if CONFIG_PPC_DCR is set

On 85xx we don't build in dcr support because the core doesn't implement the
instructions.  This caused problems when building an 85xx kernel.  Additionally
made it so we only build __mtdcr/__mfdcr if we are CONFIG_PPC_DCR_NATIVE.

The 85xx build issue wasPointed out by Dai Haruki.

Subject: [POWERPC] Generic BUG for powerpc

This makes powerpc use the generic BUG machinery.  The biggest reports the
function name, since it is redundant with kallsyms, and not needed in general.

There is an overall reduction of code, since module_32/64 duplicated several
functions.

Unfortunately there's no way to tell gcc that BUG won't return, so the BUG
macro includes a goto loop.  This will generate a real jmp instruction, which
is never used.

From: Paul Mundt <lethal@linux-sh.org>
Date: Fri, 8 Dec 2006 17:41:43 +0900
Subject: sh: BUG() handling through trapa vector.

Previously we haven't been doing anything with verbose BUG() reporting,
and we've been relying on the oops path for handling BUG()'s, which is
rather sub-optimal.

This switches BUG handling to use a fixed trapa vector (#0x3e) where we
construct a small bug frame post trapa instruction to get the context
right. This also makes it trivial to wire up a DIE_BUG for the atomic
die chain, which we couldn't really do before.

Subject: sh: Fix get_wchan().

Some time ago the schedule frame size changed and we failed to reflect
this in get_wchan() at the time. This first popped up as a problem on
SH7751R where schedule_frame ended up being unaligned and generating
an unaligned trap. This fixes it up again..

Subject: sh: Fixup sh_bios() trap handling.

This was inadvertently broken when the entry.S code split up,
restore the missing branch and get subsequent traps working
under debug again. This manifested itself as a lockup when
attempting to reload the VBR base.

Subject: [MIPS] Discard .exit.text and .exit.data at runtime.

While the recent cset 86384d544157db23879064cde36061cdcafc6794 did improve
things it didn't resolve all the problems.  So bite the bullet and discard
.exit.text and .exit.data at runtime.  Which of course sucks because it
bloats binaries with code that will never ever be used but it's the only
thing that will work reliable as demonstrated by the function sd_major() in
drivers/scsi/sd.c.

Gcc may compile sd_major() using a jump table which it will put into
.rodata.  If it also inlines sd_major's function body into exit_sd() which
gcc > 3.4.x does.  If CONFIG_BLK_DEV_SD has been set to y we would like ld
to discard exit_sd's code at link time.  However sd_major happens to
contain a switch statement which gcc will compile using a jump table in
.rodata on the architectures I checked.  So, when ld later discards
.exit.text only the jump table in .rodata with its stale references to
the discard .exit.text will be left which any no antique ld will honor
with a link error.

Subject: [MIPS] paging_init(): use highend_pfn/highstart_pfn

This patch makes paging_init() use highend_pfn/highstart_pfn globals.

It removes the need of 'high' local which was needed only by HIGHMEM config.

More important perhaps, it fixes a bug when HIGHMEM is set but there's
actually no physical highmem (highend_pfn = 0)
