This interface allows the host to override a table via a
physical address, instead of the logical address required by
acpi_os_table_override. This simplifies the host implementation.
Initial implementation by Thomas Renninger. ACPICA implementation
creates a single function for table overrides that attempts both
a logical and a physical override.

This change expands acpi_os_read_memory and acpi_os_write_memory to a
full 64 bits. This allows 64 bit transfers via the acpi_read and
acpi_write interfaces. Note: The internal acpi_hw_read and acpi_hw_write
interfaces remain at 32 bits, because 64 bits is not needed to
access the standard ACPI registers.

The RSS feature in tg3 hardware has only one rx producer ring for all
RSS rings. NAPI vector 1 is special and handles the refilling of the
rx producer ring on behalf of all RSS rings. There is a race condition
between these RSS NAPIs and the NAPI[1]. If NAPI[1] finishes checking
for refill and then another RSS ring empties the rx producer ring
before NAPI[1] exits NAPI, the chip will be completely out of SKBs in
the rx producer ring.
We fix this by adding a flag tp->rx_refill and rely on napi_schedule()/
napi_complete() to help synchronize it to close the race condition.
Update driver version to 3.123.

git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc merge from Benjamin Herrenschmidt:
"Here's the powerpc batch for this merge window. It is going to be a
bit more nasty than usual as in touching things outside of
arch/powerpc mostly due to the big iSeriesectomy :-) We finally got
rid of the bugger (legacy iSeries support) which was a PITA to
maintain and that nobody really used anymore.
Here are some of the highlights:
- Legacy iSeries is gone. Thanks Stephen ! There's still some bits
and pieces remaining if you do a grep -ir series arch/powerpc but
they are harmless and will be removed in the next few weeks
hopefully.
- The 'fadump' functionality (Firmware Assisted Dump) replaces the
previous (equivalent) "pHyp assisted dump"... it's a rewrite of a
mechanism to get the hypervisor to do crash dumps on pSeries, the
new implementation hopefully being much more reliable. Thanks
Mahesh Salgaonkar.
- The "EEH" code (pSeries PCI error handling & recovery) got a big
spring cleaning, motivated by the need to be able to implement a
new backend for it on top of some new different type of firwmare.
The work isn't complete yet, but a good chunk of the cleanups is
there. Note that this adds a field to struct device_node which is
not very nice and which Grant objects to. I will have a patch soon
that moves that to a powerpc private data structure (hopefully
before rc1) and we'll improve things further later on (hopefully
getting rid of the need for that pointer completely). Thanks Gavin
Shan.
- I dug into our exception & interrupt handling code to improve the
way we do lazy interrupt handling (and make it work properly with
"edge" triggered interrupt sources), and while at it found & fixed
a wagon of issues in those areas, including adding support for page
fault retry & fatal signals on page faults.
- Your usual random batch of small fixes & updates, including a bunch
of new embedded boards, both Freescale and APM based ones, etc..."
I fixed up some conflicts with the generalized irq-domain changes from
Grant Likely, hopefully correctly.

The oom killer chooses not to kill a thread if:
- an eligible thread has already been oom killed and has yet to exit,
and
- an eligible thread is exiting but has yet to free all its memory and
is not the thread attempting to currently allocate memory.
SysRq+F manually invokes the global oom killer to kill a memory-hogging
task. This is normally done as a last resort to free memory when no
progress is being made or to test the oom killer itself.
For both uses, we always want to kill a thread and never defer. This
patch causes SysRq+F to always kill an eligible thread and can be used to
force a kill even if another oom killed thread has failed to exit.

What it is pointed by a csrow/channel vector is a rank information, and
not a channel information.
On a traditional architecture, the memory controller directly access the
memory ranks, via chip select rows. Different ranks at the same DIMM is
selected via different chip select rows. So, typically, one
csrow/channel pair means one different DIMM.
On FB-DIMMs, there's a microcontroller chip at the DIMM, called Advanced
Memory Buffer (AMB) that serves as the interface between the memory
controller and the memory chips.
The AMB selection is via the DIMM slot, and not via a csrow.
It is up to the AMB to talk with the csrows of the DRAM chips.
So, the FB-DIMM memory controllers see the DIMM slot, and not the DIMM
rank. RAMBUS is similar.
Newer memory controllers, like the ones found on Intel Sandy Bridge and
Nehalem, even working with normal DDR3 DIMM's, don't use the usual
channel A/channel B interleaving schema to provide 128 bits data access.
Instead, they have more channels (3 or 4 channels), and they can use
several interleaving schemas. Such memory controllers see the DIMMs
directly on their registers, instead of the ranks, which is better for
the driver, as its main usageis to point to a broken DIMM stick (the
Field Repleceable Unit), and not to point to a broken DRAM chip.
The drivers that support such such newer memory architecture models
currently need to fake information and to abuse on EDAC structures, as
the subsystem was conceived with the idea that the csrow would always be
visible by the CPU.
To make things a little worse, those drivers don't currently fake
csrows/channels on a consistent way, as the concepts there don't apply
to the memory controllers they're talking with. So, each driver author
interpreted the concepts using a different logic.
In order to fix it, let's rename the data structure that points into a
DIMM rank to "rank_info", in order to be clearer about what's stored
there.
Latter patches will provide a better way to represent the memory
hierarchy for the other types of memory controller.

When i5400_edac driver is removed and re-loaded a few times, it causes
an OOPS, as it is currently decrementing some PCI device usage two
times.
When called inside a loop, pci_get_device() will call
pci_put_device(). That mangles the error count. In this specific
case, it seems easier to just duplicate the call.
Also fixes the error logic when pci_get_device fails.

Pull regulator updates for 3.4 from Mark Brown:
"This has been a fairly quiet release from a regulator point of view,
the only real framework features added were devm support and a
convenience helper for setting up fixed voltage regulators.
We also added a couple of drivers (but will drop the BQ240022 driver
via the arm-soc tree as it's been replaced by the more generic
gpio-regulator driver) and Axel Lin continued his relentless and
generally awesome stream of fixes and cleanups."

Pull irq_domain support for all architectures from Grant Likely:
"Generialize powerpc's irq_host as irq_domain
This branch takes the PowerPC irq_host infrastructure (reverse mapping
from Linux IRQ numbers to hardware irq numbering), generalizes it,
renames it to irq_domain, and makes it available to all architectures.
Originally the plan has been to create an all-new irq_domain
implementation which addresses some of the powerpc shortcomings such
as not handling 1:1 mappings well, but doing that proved to be far
more difficult and invasive than generalizing the working code and
refactoring it in-place. So, this branch rips out the 'new'
irq_domain and replaces it with the modified powerpc version (in a
fully bisectable way of course). It converts all users over to the
new API and makes irq_domain selectable on any architecture.
No architecture is forced to enable irq_domain, but the infrastructure
is required for doing OpenFirmware style irq translations. It will
even work on SPARC even though SPARC has it's own mechanism for
translating irqs at boot time. MIPS, microblaze, embedded x86 and c6x
are converted too.
The resulting irq_domain code is probably still too verbose and can be
optimized more, but that can be done incrementally and is a task for
follow-on patches."
