Some devices, like md, may create partitions only at first access,
so allow root= to be set to a valid non-existant partition of an
existing disk. This applies only to non-initramfs root mounting.
This fixes a regression from 2.6.24 which did allow this to happen and
broke some users machines :(

There is a possible data race in the page table walking code. After the split
ptlock patches, it actually seems to have been introduced to the core code, but
even before that I think it would have impacted some architectures (powerpc
and sparc64, at least, walk the page tables without taking locks eg. see
find_linux_pte()).
The race is as follows:
The pte page is allocated, zeroed, and its struct page gets its spinlock
initialized. The mm-wide ptl is then taken, and then the pte page is inserted
into the pagetables.
At this point, the spinlock is not guaranteed to have ordered the previous
stores to initialize the pte page with the subsequent store to put it in the
page tables. So another Linux page table walker might be walking down (without
any locks, because we have split-leaf-ptls), and find that new pte we've
inserted. It might try to take the spinlock before the store from the other
CPU initializes it. And subsequently it might read a pte_t out before stores
from the other CPU have cleared the memory.
There are also similar races in higher levels of the page tables. They
obviously don't involve the spinlock, but could see uninitialized memory.
Arch code and hardware pagetable walkers that walk the pagetables without
locks could see similar uninitialized memory problems, regardless of whether
split ptes are enabled or not.
I prefer to put the barriers in core code, because that's where the higher
level logic happens, but the page table accessors are per-arch, and open-coding
them everywhere I don't think is an option. I'll put the read-side barriers
in alpha arch code for now (other architectures perform data-dependent loads
in order).

Various fixes to Atmel's high speed UDC driver.
* Issue some missing disconnect() calls. Currently they are only made
when VBUS power goes away (on boards where the driver can sense such
changes), but that's not enough for gadget drivers to clean out all
the state that's needed. Missing calls were:
- After USB reset, before starting enumeration.
- When unregistering a gadget driver, before unbind().
* Don't assume gadget drivers provide disconnect callbacks; make sure
to not call through a null pointer!
* When the driver doesn't provide an unbind() callback, refuse to
unregister it.
Also remove two bogus "error" messages:
* Related to mis-handling of disconnect() ... don't emit error messages
for disconnect() handlers that disable endpoints. All of them should
be doing that; the problem is (unfixed) oddness in atmel_usba_udc.
* Don't emit a diagnostic for a curious and transient nonfatal error
that shows up sometimes with EP0.
Those messages spammed syslog, for no good reason.

Microchip has changed the PICDEM FS USB demo device (0x04d8:000c)
to use bulk transfer and not interrupt transfer. So I've updated the libusb
based program here (Post #31).
http://forum.microchip.com/tm.aspx?m=106426&mpage=2
So I believe that the in-kernel ldusb driver will no longer work with the
demo firmware. It should be removed.

Enables the SD-Card interface on the GI 0401 HSUPA card from Option.
The unusual_devs.h entry is necessary because the device descriptor is
vendor-specific. That prevents usb-storage from binding to it as an
interface driver.
This revised patch adds a small comment explaining why and reduces the
rev range.

Bugfix some serial gadget descriptors:
- Stop mangling the low bits (controller type ID) of bcdDevice;
just use the high bits for a driver revision code.
- Serial numbers that aren't specific to individual devices
are useless; stop reporting "0" for this.
- Since it's not part of a CDC-conformant function, the "bulk only"
configuration shouldn't be using "CDC Data" as its interface class.
Switch over to using CLASS_VENDOR_SPEC (different value, 0xff).

Switch serial gadget away from a *very* old idiom: just remember
the endpoints we'll be using, instead of looking them up by name
each time. This is a net code and data (globals) shrink.
Also fix a small memory leak in the rmmod path, by working the
same as the disconnect code.

This removes a needless data structure from the serial gadget code;
it's a small code shrink, and a larger data shrink.
Since "struct usb_request" already has a "struct list_head" reserved
for use by gadget drivers, the serial gadget code doesn't need to
allocate wrapper structs to hold that list ... it can (and should!)
just use the list_head provided for that exact use.

Some cleanup/reorg of g_serial ... simplifying it, and disentangling
its structure so morphing it into a "function" driver (combinable with
other interfaces) should be less painful.
- Remove most forward declarations
* put tty and gadget driver structs after their contents
* snug module init/exit decls next to their functions
* reordered some functions
- Other cleanup:
* convert a funky macro to an inline function
* snug up module params next to their declarations
* add missing driver.owner
* add separator lines between major driver sections
- Add comments re potential parameter/#define changes:
* only supports one port (shrank GS_NUM_PORTS)
* changing from 9600-8-N-1 affects multiple sites
- Remove net2280-specific optimization ... it was being done
way too late, can be done by net2280 module options, and in
any case doesn't matter at any sane serial data rates.
There are no behavioral changes, but the macro thing saves I-space.

This device is not a serial port, but a virtual CD-ROM device. For
example with my Novatel MC950D:
lsusb -v -d 1410:5010 | grep InterfaceClass
bInterfaceClass 8 Mass Storage
After some time (ca. 5min) or if virtual CD is ejected, device id
changes to 1410:4400:
% lsusb -v -d 1410:4400 | grep InterfaceClass
bInterfaceClass 255 Vendor Specific Class
bInterfaceClass 255 Vendor Specific Class
Variable name says that 0x5010 is a Novatel U727, but searching in
internet shows, that this device also provides virtual CD that should be
ejected before use. Product id for serial port in this case is 0x4100.

The patch below is a necessary workaround to support the Zoom Telephonics Model 3095F V.92 USB Mini External modem, which fails to initialise properly during normal probing thus:
May 3 22:53:00 imcfarla kernel: drivers/usb/class/cdc-acm.c: Zero length descriptor references
May 3 22:53:00 imcfarla kernel: cdc_acm: probe of 5-2:1.0 failed with error -22
Adding the patch below causes the probing section to be skipped, and the modem
then initialises correctly.

This patch (as1087d) fixes a long-standing problem in usbcore: Device,
interface, and endpoint attributes aren't added until _after_ the
creation uevent has already been broadcast.
Unfortunately there are a few attributes which cannot be created that
early. The "descriptors" attribute is binary and so must be created
separately. The power-management attributes can't be created until
the dev/power/ group exists. And the interface string can vary from
one altsetting to another, so it has to be created dynamically.

Conntrack ID is not put (anymore ?) in event messages. This causes
current ulogd2 code to fail because it uses the ID to build a hash in
userspace. This hash is used to be able to output the starting time of
a connection.
Conntrack ID can be used in userspace application to maintain an easy
match between kernel connections list and userspace one. It may worth
to add it if there is no performance related issue.

The user_regset_view table for the 32-bit regsets on the 64-bit build had
the wrong sizes for the FP regsets. This bug had no user-visible effect
(just on kernel modules using the user_regset interfaces and the like).
But the fix is trivial and risk-free.

Fix this symbol export problem:
Building modules, stage 2.
MODPOST 193 modules
ERROR: "csum_partial" [fs/reiserfs/reiserfs.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
This is due to a known weakness of symbol exports: if a symbol's
only in-core user is an EXPORT_SYMBOL from a lib-y section, the
symbol is not linked in.
The solution is to move the export to x8664_ksyms_64.c - but the real
solution would be to fix kbuild.

After resume on a 2cpu laptop, kernel builds collapse with a sed hang,
sh or make segfault (often on 20295564), real-time signal to cc1 etc.
Several hurdles to jump, but a manually-assisted bisect led to -rc1's
d2bcbad5f3ad38a1c09861bca7e252dde7bb8259 x86: do not zap_low_mappings
in __smp_prepare_cpus. Though the low mappings were removed at bootup,
they were left behind (with Global flags helping to keep them in TLB)
after resume or cpu online, causing the crashes seen.
Reinstate zap_low_mappings (with local __flush_tlb_all) for each cpu_up
on x86_32. This used to be serialized by smp_commenced_mask: that's now
gone, but a low_mappings flag will do. No need for native_smp_cpus_done
to repeat the zap: let mem_init zap BSP's low mappings just like on UP.
(In passing, fix error code from native_cpu_up: do_boot_cpu returns a
variety of diagnostic values, Dprintk what it says but convert to -EIO.
And save_pg_dir separately before zap_low_mappings: doesn't matter now,
but zapping twice in succession wiped out resume's swsusp_pg_dir.)
That worked well on the duo and one quad, but wouldn't boot 3rd or 4th
cpu on P4 Xeon, oopsing just after unlock_ipi_call_lock. The TLB flush
IPI now being sent reveals a long-standing bug: the booting cpu has its
APIC readied in smp_callin at the top of start_secondary, but isn't put
into the cpu_online_map until just before that unlock_ipi_call_lock.
So native_smp_call_function_mask to online cpus would send_IPI_allbutself,
including the cpu just coming up, though it has been excluded from the
count to wait for: by the time it handles the IPI, the call data on
native_smp_call_function_mask's stack may well have been overwritten.
So fall back to send_IPI_mask while cpu_online_map does not match
cpu_callout_map: perhaps there's a better APICological fix to be
made at the start_secondary end, but I wouldn't know that.

The qla1280 driver was ANDing the output value of mailbox register
0 with (1 << target-number) to determine whether to enable queueing
on the target in question.
But mailbox register 0 has the status code for the mailbox command
(in this case, Set Target Parameters). Potential values are:
/*
* ISP mailbox command complete status codes
*/
So clearly that is in error. I can't think what the author of that
line was looking for in a mailbox register, so I just eliminated the
AND. flag is used later in the function, and I think that the later
usage was also wrong, though it was used to set values that aren't
used. Oh well, an overhaul of this driver is not what I want to do
now -- just a bugfix.
After the fix, I found that my disks were getting a queue depth of
255, which is far too many. Most SCSI disks are limited to 32 or
64. In any case, there's no point, queueing up a bunch of commands
to the adapter that will just result in queue full or starve other
targets from being issued commands due to running out of internal
memory. So I dropped default queue depth to 32 (from which 1 is
subtracted elsewhere, giving net of 31).
I tested with a Seagate ST336753LC, and results look good, so
I'm satisfied with this patch.

The acpi_query_osc() function can be called for the ACPI object that
doesn't have _OSC method. In this case, acpi_get_osc_data() would
allocate a useless memory region. To avoid this, we need to check the
existence of _OSC before calling acpi_get_osc_data() in acpi_query_osc().

Some versions of X used the mprotect workaround to change caching type from UC
to WB, so that it can then use mtrr to program WC for that region [1]. Change
the mmap of pci space through /sys or /proc interfaces from UC to UC_MINUS.
With this change, X will not need to use mprotect workaround to get WC type
since the MTRR mapping type will be honored.
The bug in mprotect that clobbers PAT bits is fixed in a follow on patch. So,
this X workaround will stop working as well.

This applies the NVidia MSI enabled flag for HT capable devices quirk
to ALi bridges as well.
As described in more detail in http://bugzilla.kernel.org/show_bug.cgi?id=10667
this is required for my board which is using an nForce 3 250Gb chipset with an
ALi M1695 northbridge.
It fixes a regression introduced in 2.6.24 that made the internal NIC of the
board unusable (MSI initialisation of the NIC but disabled MSI on the
northbridge devices.
