af829310e8 ARM: pxa: fix invalid mfp pin issue
Failure is reported on hx4700 with kernel v3.3-rc1.

__mfp_validate: GPIO20 is invalid pin
__mfp_validate: GPIO21 is invalid pin
__mfp_validate: GPIO15 is invalid pin
__mfp_validate: GPIO78 is invalid pin
__mfp_validate: GPIO79 is invalid pin

__mfp_validate: GPIO33 is invalid pin
__mfp_validate: GPIO48 is invalid pin
__mfp_validate: GPIO49 is invalid pin
__mfp_validate: GPIO50 is invalid pin

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.

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.

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.

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.

d5a74afd08 IOMMU fixes for Linux 3.3-rc5
All the fixes are for the OMAP IOMMU driver. The first patch is the
 biggest one. It fixes the calls of the function omap_find_iovm_area() in
 the omap-iommu-debug module which expects a 'struct device' parameter
 since commit fabdbca instead of an omap_iommu handle. The
 omap-iommu-debug code still passed the handle to the function which
 caused a crash.
 The second patch fixes a NULL pointer dereference in the OMAP code and
 the third patch makes sure that the omap-iommu is initialized before the
 omap-isp driver, which relies on the iommu. The last patch is only a
 workaround until defered probing is implemented.

Otherwise we can get the following warning on some compilers:

arch/arm/mach-omap2/board-omap3evm.c:384:11:
warning: array subscript is above array bounds

The omap3evm BSP enables a GPIO LED on the twl4030 chip.  However,
the static gpio_leds array doesn't have an entry for it.  This is
most likely a copy-and-paste error, because it has been in there
since the first commit of the omap3evm BSP (53c5ec31).

(They both provided patches to fix it)

This patch also (at the request of the list) fixes the fact that
ARM has both LE and BE versions however the audit code was called as if
it was always BE.  If audit userspace were to try to interpret the bits
it got from a LE system it would obviously do so incorrectly.  Fix this
by using the right arch flag on the right system.

e23e8c0690 ARM/PCI: Remove ARM's duplicate definition of 'pcibios_max_latency'
The patch series to re-factor PCI's 'latency timer' setup (re:
http://marc.info/?l=linux-kernel&m=131983853831049&w=2) forgot to
remove the ARM specific definition of 'pcibios_max_latency' once such
had been moved into the pci core resulting in ARM related compile
errors -
  drivers/built-in.o:(.data+0x230): multiple definition of
  `pcibios_max_latency'
  arch/arm/common/built-in.o:(.data+0x40c): first defined here
  make[1]: *** [vmlinux.o] Error 1

In the series, patch 2/16 (commit 168c8619fd) converted the ARM
specific version of 'pcibios_set_master()' to a non-inlined version.
This was done in preperation for hosting it up into PCI's core, which
was done in patch 10/16 (commit 96c5590058) of the series (and
where the removal of ARM's 'pcibios_max_latency' was overlooked).

910ba598c8 ARM: 7336/1: smp_twd: Don't register CPUFREQ notifiers if local timers are not initialised
Current ARM local timer code registers CPUFREQ notifiers even in case
the twd_timer_setup() isn't called. That seems to be wrong and
would eventually lead to kernel crash on the CPU frequency transitions
on the SOCs where the local timer doesn't exist or broken because of
hardware BUG. Fix it by testing twd_evt and *__this_cpu_ptr(twd_evt).

The issue was observed with v3.3-rc3 and building an OMAP2+ kernel
on OMAP3 SOC which doesn't have TWD.

Below is the dump for reference :

97899e555b ARM: OMAP: Fix kernel panic with HSMMC when twl4030_gpio is a module
On some omaps twl4030_gpio has a callback to try to initialize
the MMC controller. If twl4030_gpio is compiled as a module,
bad things can happen because the callback function starts
calling functions that are supposed to be marked __init:

Kernel panic - not syncing: Attempted to kill the idle task!
twl4030_gpio twl4030_gpio: can't dispatch IRQs from modules
gpiochip_add: registered GPIOs 192 to 209 on device: twl4030
Unable to handle kernel paging request at virtual address b82a4c74
...

Additionally if this does not fail, warnings are produced
about trying to register the MMC multiple times.

Fix this by removing __init from omap_mux_get_by_name,
and add checks if omap2_hsmmc_init() is getting called more
than once.

Note that this will get fixed properly later on by splitting
omap2_hsmmc_init into two functions.

be2874cb4e These are the bug fixes that have accumulated since 3.3-rc3 in arm-soc.
The majority of them are regression fixes for stuff that broke during
 the merge 3.3 window.
 
 The notable ones are:
 
 * The at91 ata drivers both broke because of an earlier cleanup patch that
   some other patches were based on. Jean-Christophe decided to remove
   the legacy at91_ide driver and fix the new-style at91-pata driver while
   keeping the cleanup patch. I almost rejected the patches for being too
   late and too big but in the end decided to accept them because they
   fix a regression.
 
 * A patch fixing build breakage from the sysdev-to-device conversion
   colliding with other changes touches a number of mach-s3c files.
 
 * b0654037 "ARM: orion: Fix Orion5x GPIO regression from MPP cleanup"
   is a mechanical change that unfortunately touches a lot of lines
   that should up in the diffstat.
