8e73e367f7 ARM: SoC cleanups for 3.12
This branch contains code cleanups, moves and removals for 3.12.
 
 There's a large number of various cleanups, and a nice net removal of
 13500 lines of code.
 
 Highlights worth mentioning are:
 
 - A series of patches from Stephen Boyd removing the ARM local timer API.
 - Move of Qualcomm MSM IOMMU code to drivers/iommu.
 - Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver
   and switching over to the drivers/pwm one.
 - Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
 
 There's also a move of a header file out of include/linux/i2c/ to
 platform_data, where it really belongs. It touches mostly ARM platform
 code for include changes so we took it through our tree.

bfaddb7d13 msm_serial: Switch clock consumer strings and simplify code
In downstream kernel we've standardized the clock consumer names
that MSM device drivers use. Replace the uart specific clock
names in this driver with the more standard 'core' and 'iface'
names. Also simplify the code by assuming that clk_prepare_enable
and clk_disable_unprepare() will properly check for NULL pointers
(it will because MSM uses the common clock framework).

3294a7e7c3 ARM: msm: Only compile io.c on platforms that use it
Only the non-dt based MSM platforms need to map memory from their
machine descriptor. Unfortunately it is always compiled if
ARCH_MSM=y and the file also has mach/ includes in it. Since
dt-based MSM platforms aren't actually using anything in this
file just compile io.c on the non-dt based MSM platforms. This
allows the dt-based platforms to participate in the
multi-platform kernel.

The iommu devices are registered in software, when they should

because these devices aren't probing today due to missing clocks.

Two small fixes for MSM.
 
 The first fixes the a gpio controller register address.  I didn't see
 any acks from the devicetree maintainers, so I've copied them on this
 pull request.  The change itself is minor, and just to the register
 address.
 
 The second change removes the gpiomux V1 code from MSM.  This was
 breaking compilation for some of the targets.

8bd26e3a7e arm: delete __cpuinit/__CPUINIT usage from all ARM users
The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
and are flagged as __cpuinit  -- so if we remove the __cpuinit from
the arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
related content into no-ops as early as possible, since that will get
rid of these warnings.  In any case, they are temporary and harmless.

This removes all the ARM uses of the __cpuinit macros from C code,
and all __CPUINIT from assembly code.  It also had two ".previous"
section statements that were paired off against __CPUINIT
(aka .section ".cpuinit.text") that also get removed here.

 "This contains the usual updates from other people (listed below) and

  low priority bug fixes and performance improvements.

  I've started to put the pull request wording into the merge commits,

   - NoMMU stuff:

     This includes the following series sent earlier to the list:

     This is rebased (and re-tested) on your devel-stable branch because
     otherwise there were going to be conflicts with Uwe's V7M work now
     that you've merged that.  I've included the fix for limiting MPU to
     CPU_V7.

     These changes bring both HugeTLB support and Transparent HugePage
     (THP) support to ARM.  Only long descriptors (LPAE) are supported
     in this series.

     The code has been tested on an Arndale board (Exynos 5250).

     while.  They're the same as my last posting, but have been rebased
     to v3.10-rc3.

   - mpidr linearisation (multiprocessor id register - identifies which
     CPU number we are in the system)

     This patch series that implements MPIDR linearization through a
     simple hashing algorithm and updates current cpu_{suspend}/{resume}
     code to use the newly created hash structures to retrieve context
     pointers.  It represents a stepping stone for the implementation of
     power management code on forthcoming multi-cluster ARM systems.

     It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
     OMAP4 and Tegra, with processors hitting low-power states requiring
     warm-boot resume through the cpu_resume code path"

42daabf62b ARM SoC late changes
These are changes that arrived a little late before the merge
 window or that have multiple dependencies on previous branches
 so they did not fit into one of the earlier ones. There
 are 10 branches merged here, a total of 39 non-merge commits.
 Contents are a mixed bag for the above reasons:
 
 * Two new SoC platforms: ST microelectronics stixxxx and
   the TI 'Nspire' graphing calculator. These should have
   been in the 'soc' branch but were a little late
 * Support for the Exynos 5420 variant in mach-exynos,
   which is based on the other exynos branches to avoid
   conflicts.
 * Various small changes for sh-mobile, ux500 and davinci
 * Common clk support for MSM
 
 Conflicts:
 * In Kconfig.debug, various additions trivially conflict,
   the list should be kept in alphabetical order when
   resolving.

8cc7f5338e ARM: msm: Migrate to common clock framework
Move the existing clock code in mach-msm to the common clock
framework. We lose our capability to set the rate of and enable a
clock through debugfs. This is ok though because the debugfs
features are mainly used for testing and development of new clock
code.

To maintain compatibility with the original MSM clock code we
make a wrapper for clk_reset() that calls the struct msm_clk
specific reset function. This is necessary for the usb and sdcc
devices on MSM until a better suited API is made available.

 patch in this branch to a early version of multiplatform conversion,
 but it ended up being reverted due to need of more bake time. The
 revert commit is part of the branch since it would have required

4d26aa3054 ARM: arm-soc non-critical fixes for 3.10
Here is a collection of fixes (and some intermixed cleanups) that were
 considered less important and thus not included in the later parts of
 the 3.9-rc cycle.
 
 It's a bit all over the map, contents wise. A series of ux500 fixes
 and cleanups, a bunch of various fixes for OMAP and tegra, and some for
 Freescale i.MX and even Qualcomm MSM.
 
 Note that there's also a patch on this branch to globally turn off
 -Wmaybe-uninitialized when building with -Os. It's been posted several
 times by Arnd and no dissent was raised, but nobody seemed interested
 to pick it up. So here it is, as the topmost patch.

73a8c28f16 ARM: msm: Fix uncompess.h tx underrun check
Bit 3 of the SR register is set if there is a tx underrun. If
this bit isn't set, we should loop on the tx ready bit until we
can transmit again. Otherwise we should skip the loop and
transmit immediately. The code is doing the opposite though,
checking for an underrun and then looping on the tx ready bit
causing us to never loop on the tx read bit when the tx buffer
may not be ready.

This doesn't seem to affect my 8960 device too often, but in some
cases I see a lost character or two from the decompressor prints.
This also matches what we do in the assembly in debug-macro.S.

4c3ffffdbc ARM: Push selects for TWD/SCU into machine entries
The TWD and SCU configs are selected by default as long as
MSM_SCORPIONMP is false and/or MCT is false. Implementing the
logic this way certainly saves lines in the Kconfig but it
precludes those machines which select MSM_SCORPIONMP or MCT from
participating in the single zImage effort because when those
machines are combined with other SMP capable machines the TWD and
SCU are no longer selected by default.

Push the select out to the machine entries so that we can compile
these machines together and still select the appropriate configs.
