Rework the PS3 system bus to unify device support.
- DMA region sizes must be a power of two
- storage bus DMA updates:
- Small fixes for the PS3 DMA core:
o fix alignment bug
o kill superfluous test
o indentation
o spelling
o export ps3_dma_region_{create,free}()
- ps3_dma_region_init():
o Add `addr' and `len' parameters, so you can create a DMA region that
does not cover all memory (use `NULL' and `0' to cover all memory).
This is needed because there are not sufficient IOMMU resources to have
all DMA regions cover all memory.
o Uninline
- Added remove and shutdown routines to all drivers.
- Added loadable module support to all drivers.
- Added HV calls for iopte management (needed by sound driver).

On Power machines supporting VRMA, Kexec/Kdump does not work.
VRMA (virtual real-mode area) means that accesses with IR/DR = 0
(i.e. the MMU "off") actually still go through the hash table,
using entries put there by the hypervisor.
This means that when we clear out the hash table on kexec, we need to
make sure these entries are left untouched.
This also adds plpar_pte_read_raw() on the lines of
plpar_pte_remove_raw().

In some of the PPC970 based systems, interrupt would be distributed to
offline cpus also even when booted with "maxcpus=1". So check whether
cpu online map and cpu present map are equal or not. If they are equal
default_distrib_server is used as interrupt server otherwise boot cpu
(default_server) used as interrupt server.
In addition to this, if an interrupt is assigned to a specific cpu (ie
smp affinity) and if that cpu is not online, the earlier code used to
return the default_distrib_server as interrupt server. This
introduces an additional parameter to the get_irq function, called
strict_check. Based on this parameter, if the cpu is not online
either default_distrib_server or -1 is returned.

There are 2 config options that indicate whether the platform being built
has a device tree source file associated with it. Namely,
CONFIG_WANT_DEVICE_TREE and CONFIG_DEVICE_TREE. When CONFIG_WANT_DEVICE_TREE
is 'y' and CONFIG_DEVICE_TREE isn't an empty string, automatically wrap
the specified device tree with the zImage being built.
To achieve this, the 'dts' variable will only be set when the conditions
above are true. The changes to the zImage.initrd.% and zImage.% rules
cause the device tree to be wrapped when 'dts' is set; otherwise, they
will work as they previosly did (i.e., build a zImage with no device tree).

cpu_purr_data is a per-cpu array used to account for stolen time on
partitioned systems. It used to be the case that cpus accessed each
others' cpu_purr_data, so each entry was protected by a spinlock.
However, the code was reworked ("Simplify stolen time calculation")
with the result that each cpu accesses its own cpu_purr_data and not
those of other cpus. This means we can get rid of the spinlock as
long as we're careful to disable interrupts when accessing
cpu_purr_data in process context.

With both generic rtc and powerpc timer suspend / resume code now in the
(powerpc.git) tree, powerpc platforms using the generic timer and enabling
power management will have timer.o linked in the kernel, which they don't
need. Moreover, it will likely WARN_ON(!ppc_md.get_rtc_time), save
zero-time and return no error on suspend...
As a possible solution we can choose not to build timer.o when RTC_CLASS
is enabled. However, I can imagine systems with 2 rtc's, one served by the
ppc-rtc, another one generic built as a module, in which case using the
ppc-rtc for suspend / resume will be impossible. Not to say, that such a
configuration would be ugly...

Glue code to hook up the pata_platform on the PA Semi Electra eval board.
CFE sets up device tree entries for the IDE interface, with device type
'ide' and compatible field 'electra-ide'.
We unfortunately need to modify the resources before calling the generic
platform driver, since the device tree only has one register window in
it and the driver expects two. Adding this as an of_platform driver
instead doesn't give us any benefit, it just adds one more layer of
register/probe functions.
Since CONFIG_PATA_PLATFORM depends on CONFIG_EMBEDDED, add that as a
default for PPC_PASEMI.

With this, when kexec-ing, we copy the code and start the slaves on
their journey to the next kernel's spin loop as soon as we copy the
kexec image into place.
The kernel doesn't know exactly which slaves are spinning in
kexec_wait. This allows us to pass more than max-cpus to the
next kernel. But it also means that we might leave some behind.
Moving the code here means they have the time it takes us to
clear the hash table to wake up and move on. Moving the code
any earlier would reuqire walking the image description to
search for the code, which could span multiple pages.

This fixes some problems with the way the some things
represented in the device tree for the Holly and Taiga boards. This
means changes both to the dts files, and to the code which
instantiates the tsi108 ethernet platform devices based on the device
tree.
- First, and most importantly, the ethernet PHYs are given
with an identical 'reg' property. This reg currently encodes the
accessible register used to initiate mdio interaction with the PHYs,
rather than a meaningful address on the parent bus (mdio in this
case), which is incorrect. Instead we give the address of these
registers as 'reg' in the mdio node itself, and encode the ID of each
phy in their 'reg' propertyies.
- Currently the platform device constructor enables a
workaround in the tsi108 ethernet driver based on the compatible
property of the PHY. This is incorrect, because the workaround in
question is necessary due to the board's wiring of the PHY, not the
model of PHY itself. This patch alters the constructor to instead
enable the workaround based on a new special property in the PHY node.
- The compatible properties on a number of nodes in the device
tree are insufficiently precise. In particular the PHYs give only
"bcm54xx", which is broken, since there are many bcm54xx PHY models,
and they have differences which matter. The mdio had a compatible
property of "tsi-ethernet" identical to the ethernet MAC nodes, which
doesn't make sense. The ethernet, i2c, bridge and PCI nodes were
given only as "tsi-*" which is somewhat inprecise, we replace with
"tsi108-*" in the case of Taiga (which has a TSI108 bridge), and
"tsi109-*", "tsi108-*" in the case of Holly (which has a TSI109
bridge).
- We remove some "model" properties from the ethernets on
Taiga board which were neither useful nor adequately precise.
- On Holly we change to using a dtc label instead of a full
path to reference the MPIC node, which makes the dts a little more
readable.

Currently, the Holly device tree includes a bootargs property in
/chosen, which gives a commandline. This is somewhat inconvenient,
because it means an alternative default command line can't be given in
the kernel config - the value obtained from the dts via the
bootwrapper will always override CONFIG_CMDLINE.
This removes the command line from the dts, and instead puts the
same command line as a default in holly_defconfig.

The various cuboot platforms (i.e. pre-device tree aware u-boot for
83xx, 85xx and Ebony) share a certain amount of code for parsing the
boot parameters. To a certain extent that's inevitable, since they
platforms have different definitions of the bd_t structure. However,
with some macro work and a helper function, this patch improves the
situation a bit.
In the process, this fixes a bug on Ebony, which was incorrectly
handling the parameters passed form u-boot for the command line (the
bug was copied from 83xx and 85xx which have subsequently been fixed).

In the device tree for Ebony, the 'ranges' property in the node for
the EBC bridge shows the mappings from the chip select / address lines
actually used for the EBC peripherals into the address space of the
OPB. At present, these mappings are hardcoded in ebony.dts for the
mappings set up by the OpenBIOS firmware when it configures the EBC
bridge.
This replaces the hardcoded mappings with code in the zImage to
read the EBC configuration registers and create an appropriate ranges
property based on them. This should make the zImage and kernel more
robust to changes in firmware configuration. In particular, some of
the Ebony's DIP switches can change the effective address of the Flash
and other peripherals in OPB space. With this patch, the kernel will
be able to cope with at least some of the possible variations.

Currently the powerpc kernel has a 64-bit only feature,
COHERENT_ICACHE used for those CPUS which maintain icache/dcache
coherency in hardware (POWER5, essentially). It also has a feature,
SPLIT_ID_CACHE, which is used on CPUs which have separate i and
d-caches, which is to say everything except 601 and Freescale E200.
In nearly all the places we check the SPLIT_ID_CACHE, what we actually
care about is whether the i and d-caches are coherent (which they will
be, trivially, if they're the same cache).
This tries to clarify the situation a little. The COHERENT_ICACHE
feature becomes availble on 32-bit and is set for all CPUs where i and
d-cache are effectively coherent, whether this is due to special logic
(POWER5) or because they're unified. We check this, instead of
SPLIT_ID_CACHE nearly everywhere.
The SPLIT_ID_CACHE feature itself is replaced by a UNIFIED_ID_CACHE
feature with reversed sense, set only on 601 and Freescale E200. In
the two places (one Freescale BookE specific) where we really care
whether it's a unified cache, not whether they're coherent, we check
this feature. The CPUs with unified cache are so few, we could
consider replacing this feature bit with explicit checks against the
PVR.
This will make unifying the 32-bit and 64-bit cache flush code a
little more straightforward.

Using typedefs to rename structure types if frowned on by CodingStyle.
However, we do so for the hash PTE structure on both ppc32 (where it's
called "PTE") and ppc64 (where it's called "hpte_t"). On ppc32 we
also have such a typedef for the BATs ("BAT").
This removes this unhelpful use of typedefs, in the process

Killing just one of the process threads can leave the application in a
bad state, whereas killing the entire process group would allow for
the application to restart, or be otherwise handled, and makes it very
obvious that something has gone wrong.
This change allows the entire process group to be taken down, rather than

A Power6 can give up CPU cycles on a dedicated CPU (as opposed to a
shared CPU) to other shared processors if the administrator asks for it
(via the HMC).
This enables that to work properly on P6.
This just involves setting a bit in the CAS structure as well as the
VPA. To donate cycles, a CPU has to have all SMT threads idle and
have the donate bit set in the VPA. Then call H_CEDE.
The reason why shared processors just aren't used is because dedicated
CPUs are guaranteed an actual processor, yet the system is still able to
increase the capacity of the shared CPU pool.
Also rename the VPA's cpuctls_task_attrs field to a more accurate name.
