Magnus Damm 03f7beeff4 ARM: mach-shmobile: sh7377 and G4EVM timer rework
Move the SoC specific timer code from G4EVM board code
to sh7377 setup code. This makes is possible to share
the SoC specific timer code across boards and it also
removes the need for a board specific timer structure.

Linus Torvalds 0cacaf51a0 IOMMU fixes for Linux v3.3-rc6
Two fixes are queued up. The first is an additional fix for the OMAP
 initialization order issue and the second patch fixes a possible section
 mismatch which can lead to a kernel crash in the AMD IOMMU driver when
 suspend/resume is used and the compiler has not inlined the
 iommu_set_device_table function.

Lorenzo Pieralisi a0feb6db0f ARM: 7358/1: perf: add PMU hotplug notifier
When a CPU is taken out of reset, either cold booted or hotplugged in,
some of its PMU registers can contain UNKNOWN values.

This patch adds a hotplug notifier to ARM core perf code so that upon
CPU restart the PMU unit is reset and becomes ready to use again.

Will Deacon 3f31ae1213 ARM: 7357/1: perf: fix overflow handling for xscale2 PMUs
xscale2 PMUs indicate overflow not via the PMU control register, but by
a separate overflow FLAG register instead.

This patch fixes the xscale2 PMU code to use this register to detect
to overflow and ensures that we clear any pending overflow when
disabling a counter.

Will Deacon f6f5a30c83 ARM: 7356/1: perf: check that we have an event in the PMU IRQ handlers
The PMU IRQ handlers in perf assume that if a counter has overflowed
then perf must be responsible. In the paranoid world of crazy hardware,
this could be false, so check that we do have a valid event before
attempting to dereference NULL in the interrupt path.

When disabling a counter on an ARMv7 PMU, we should also clear the
overflow flag in case an overflow occurred whilst stopping the counter.
This prevents a spurious overflow being picked up later and leading to
either false accounting or a NULL dereference.

Will Deacon 5727347180 ARM: 7354/1: perf: limit sample_period to half max_period in non-sampling mode
On ARM, the PMU does not stop counting after an overflow and therefore
IRQ latency affects the new counter value read by the kernel. This is
significant for non-sampling runs where it is possible for the new value
to overtake the previous one, causing the delta to be out by up to
max_period events.

Commit a737823d ("ARM: 6835/1: perf: ensure overflows aren't missed due
to IRQ latency") attempted to fix this problem by allowing interrupt
handlers to pass an overflow flag to the event update function, causing
the overflow calculation to assume that the counter passed through zero
when going from prev to new. Unfortunately, this doesn't work when
overflow occurs on the perf_task_tick path because we have the flag
cleared and end up computing a large negative delta.

This patch removes the overflow flag from armpmu_event_update and
instead limits the sample_period to half of the max_period for
non-sampling profiling runs.

Since pxa_last_gpio is used in mfp-pxa2xx driver. But it's only
updated in pxa-gpio driver that run after mfp-pxa2xx driver.

So update the pxa_last_gpio first in mfp-pxa2xx driver.

Haojian Zhuang 0c7de34be3 ARM: pxa: remove duplicated registeration on pxa-gpio
Both reboot (via reboot(RB_AUTOBOOT)) and suspend freeze on hx4700.

Registration of pxa_gpio_syscore_ops is moved into pxa-gpio driver,
but it still exists in arch-pxa directory. It resulsts failure on
reboot and suspend.

Now remove the registration code in arch-pxa.

Haojian Zhuang bbdc818b27 ARM: pxa: add dummy clock for pxa25x and pxa27x
gpio-pxa driver is shared among arch-pxa and arch-mmp. Clock is the
essential component on pxa3xx/pxa95x and arch-mmp. So we need to
define dummy clock in pxa25x/pxa27x instead.

This regression was introduced by the commit "ARM: pxa: add dummy
clock for sa1100-rtc", id a55b5adaf4.

Heiko Stuebner c1ba544f81 ARM: S3C24XX: Fix restart on S3C2442
Commit b27b072791 (ARM: 7265/1: restart: S3C24XX: use new restart hook)
introduced the new restart hook also for the S3C244x cpus, but it
was only defined in the S3C2440 scope, i.e. when CPU_S3C2440 was
selected. Devices using the S3C2442 like the GTA02 normally don't select
this CPU which leads to compilation errors like:
    LD      .tmp_vmlinux1
  arch/arm/mach-s3c2440/built-in.o:(.arch.info.init+0x3c): undefined reference
to `s3c2440_restart'
  make: *** [.tmp_vmlinux1] Error 1

Therefore move the s3c2440_restart function to s3c244x.c which is
common to both cpus and also fix the naming to reflect this.

Cousson, Benoit 5a3ff8473c ARM: OMAP: irqs: Fix NR_IRQS value to handle PRCM interrupts
The following commit: 2f31b51659
Author: Tero Kristo <t-kristo@ti.com>
Date:   Fri Dec 16 14:37:00 2011 -0700

    ARM: OMAP4: PRM: use PRCM interrupt handler

introduced the PRCM interrupt handler and thus the need
for 64 more interrupts. Since SPARSE_IRQ is still not fully
functional on OMAP, the NR_IRQS needs to be updated to avoid
the failure that happen during irq_alloc_descs call inside
the PRCM driver:

[    0.208221] PRCM: failed to allocate irq descs: -12

Later the mux framework is then unable to request an IRQ from
the PRCM interrupt handler.

[    1.802795] mux: Failed to setup hwmod io irq -22

Fix that by adding 64 more interrupts for OMAP2PLUS config.
