We can run a 32-bit kernel on boxes with an IOMMU, so we need
pci_unmap_addr() etc. to work -- without it, drivers will leak mappings.
To be honest, this whole thing looks like it's more pain than it's
worth; I'm half inclined to remove the no-op #else case altogether.
But this is the minimal fix, which just does the right thing if
CONFIG_DMAR is set.

Previous code made an assumption that the power on value of global
control MSR has enabled all fixed and general purpose counters properly.
However, this is not the case for certain Intel processors, such as
Atom - and it might also be firmware dependent.
Each enable bit in IA32_PERF_GLOBAL_CTRL is AND'ed with the
enable bits for all privilege levels in the respective IA32_PERFEVTSELx
or IA32_PERF_FIXED_CTR_CTRL MSRs to start/stop the counting of
respective counters. Counting is enabled if the AND'ed results is true;
counting is disabled when the result is false.
The end result is that all fixed counters are always disabled on Atom
processors because the assumption is just invalid.
Fix this by not initializing the ctrl-mask out of the global MSR,
but setting it to perf_counter_mask.

* 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6:
Add Fenghua Yu as temporary co-maintainer for ia64
[IA64] address compiler warnings perfmon.c/salinfo.c
[IA64] Remove unnecessary semicolons
[IA64] sprintf should not be used with same source & destination address

perfmon.c has a dubious cast directly from "int" to "void *". Add
an intermediate cast to "long" to keep gcc happy.
salinfo.c uses "down_trylock()" in a highly creative way (explained
in the comments in the file) ... but it does kick out this warning:
arch/ia64/kernel/salinfo.c:195: warning: ignoring return value of 'down_trylock'
which people occasionally try to "fix" in ways that do not work. Use some
casts to keep gcc quiet.

| page-allocator: clear N_HIGH_MEMORY map before we set it again
|
| SRAT tables may contains nodes of very small size. The arch code may
| decide to not activate such a node. However, currently the early boot
| code sets N_HIGH_MEMORY for such nodes. These nodes therefore seem to be
| active although these nodes have no present pages.
|
| For 64bit N_HIGH_MEMORY == N_NORMAL_MEMORY, so that works for 64 bit too
unintentionally and incorrectly clears the cpuset.mems cgroup attribute on
an i386 kvm guest, meaning that cpuset.mems can not be used.
Fix this by only clearing node_states[N_NORMAL_MEMORY] for 64bit only.
and need to do save/restore for that in find_zone_movable_pfn

alpha percpu access requires custom SHIFT_PERCPU_PTR() definition for
modules to work around addressing range limitation. This is done via
generating inline assembly using C preprocessing which forces the
assembler to generate external reference. This happens behind the
compiler's back and makes the compiler think that static percpu variables
in modules are unused.
This used to be worked around by using __unused attribute for percpu
variables which prevent the compiler from omitting the variable; however,
recent declare/definition attribute unification change broke this as
__used can't be used for declaration. Also, in the process,
PER_CPU_ATTRIBUTES definition in alpha percpu.h got broken.
This patch adds PER_CPU_DEF_ATTRIBUTES which is only used for definitions
and make alpha use it to add __used for percpu variables in modules. This
also fixes the PER_CPU_ATTRIBUTES double definition bug.

Update the link script for ARM to use PAGE_SIZE instead of hard-
coded 4096. Also the old RODATA macro is deprecated
for the RO_DATA(PAGE_SIZE) macro. As a consequence the PAGE_SIZE
was changed from (1UL << PAGE_SHIFT) to (_AC(1,UL) << PAGE_SHIFT)
because the linker does not understand the "UL" suffix to numeric
constants.

platform devices, but these do not build on s3c24xx systems
and the file depends on SND_S3C24XX_SOC, which is selected

The omap_type() function is added and returns the DEVICETYPE field of
the CONTROL_STATUS register. The result can be used for conditional
code based on whether device is GP (general purpose), EMU or
HS (high security). Also move the type defines so omap1 code
compile does not require ifdefs for sections using these defines.
This code is needed for the following fix to set the SRAM
size correctly for HS omaps. Also at least PM and watchdog
code will need this function.

twl_mmc23_set_power() has MMC2 twl_mmc_controller hardcoded in it, which
breaks MMC3. Find the right controller to use instead.

Some of the N770's MMC configuration options seem to have been
dropped. This patch adds them back in again.
Note that only the .ocr_mask change was /critical/, but I've added the
.max_freq setting back as well, as the original sources had it. Can
anyone confirm if this is unnecessary?
Secondly, there is support in the original code for a 4wire/higher
speed mode. As I don't have the requisite N770 hardware (I think it
was a rev2 N770?) to test this, I can't really add it back.

causing a build failure on latest git with CONFIG_OMAP_MBOX_FWK=m; the
original breakage appears to date from the end of last year in

This reverts commit 95ee14e4379c5e19c0897c872350570402014742.
Mikael Petterson <mikepe@it.uu.se> reported that at least one of his
systems will not boot as a result. We have ruled out the detection
algorithm malfunctioning, so it is not a matter of producing the
incorrect bitmasks; rather, something in the application of them
fails.
Revert the commit until we can root cause and correct this problem.
-stable team: this means the underlying commit should be rejected.

In commit 7fe29e0faacb650d31b9e9f538203a157bec821d we ignored the
reads to the P6 EVNTSEL MSRs. That fixed crashes on Intel machines.
Ignore the reads to K7 EVNTSEL MSRs as well to fix this on AMD
hosts.
This fixes Kaspersky antivirus crashing Windows guests on AMD hosts.

IF a guest tries to use vmx instructions, inject a #UD to let it know the
instruction is not implemented, rather than crashing.
This prevents guest userspace from crashing the guest kernel.

2.6.31-rc introduced an architecture level set checker based on facility
bits. e.g. if the kernel is compiled to run only on z9, several facility
bits are checked very early and the kernel refuses to boot if a z9 specific
facility is missing.
Until now kvm on s390 did not implement the store facility extended (STFLE)
instruction. A 2.6.31-rc kernel that was compiled for z9 or higher did not
boot in kvm. This patch implements stfle.
This patch should go in before 2.6.31.
