37820108f3 ARM: soc: Fixes for 3.7-rc2
A set of fixes and some minor cleanups for -rc2:
 
 - A series from Arnd that fixes warnings in drivers and other code
   included by ARM defconfigs. Most have been acked by corresponding
   maintainers (and seem quite hard to argue not picking up anyway in the
   few exception cases).
 - A few misc patches from the list for integrator/vt8500/i.MX
 - A batch of fixes to OMAP platforms, fixing:
   - boot problems on beaglebone,
   - regression fixes for local timers
   - clockdomain locking fixes
   - a few boot/sparse warnings
 - For Tegra:
   - Clock rate calculation overflow fix
   - Revert a change that removed timer clocks and a fix for symbol name clashes
 - For Renesas:
   - IO accessor / annotation cleanups to remove warnings
 - For Kirkwood/Dove/mvebu:
   - Fixes for device trees for Dove (some minor cleanups, some fixes)
   - Fixes for the mvebu gpio driver
   - Fix build problem for Feroceon due to missing ifdefs
   - Fix lsxl DTS files

ee7b5958e2 xen: arm: make p2m operations NOPs
This makes common code less ifdef-y and is consistent with PVHVM on
x86.

Also note that phys_to_machine_mapping_valid should take a pfn
argument and make it do so.

Add __set_phys_to_machine, make set_phys_to_machine a simple wrapper
(on systems with non-nop implementations the outer one can allocate
new p2m pages).

Make __set_phys_to_machine check for identity mapping or invalid only.

ef32f89298 xen: grant: use xen_pfn_t type for frame_list.
This correctly sizes it as 64 bit on ARM but leaves it as unsigned
long on x86 (therefore no intended change on x86).

The long and ulong guest handles are now unused (and a bit dangerous)
so remove them.

4cc3c840cb ARM: mach-imx: Fix selection of ARCH_MXC
Since commit c5a0d497(ARM: imx: enable multi-platform build),
ARCH_MXC is selected by the following logic:

config ARCH_MXC
        def_bool y if ARCH_MULTI_V4_V5 || ARCH_MULTI_V6_V7

, which causes build error on vexpress_defconfig:

arch/arm/mach-imx/hotplug.c:49: undefined reference to `imx_enable_cpu'
arch/arm/mach-imx/platsmp.c:57: undefined reference to `imx_set_cpu_jump'
arch/arm/mach-imx/platsmp.c:58: undefined reference to `imx_enable_cpu'

Make ARCH_MXC a user selectable option, so that it does not get built
by default on other defconfigs that select ARCH_MULTI_V4_V5 or ARCH_MULTI_V6_V7.

e4c060db2c ARM: OMAP: Split plat/cpu.h into local soc.h for mach-omap1 and mach-omap2
We want to remove plat/cpu.h. To do this, let's first split
it to private soc.h to mach-omap1 and mach-omap2. We have to
keep plat/cpu.h around until the remaining drivers are fixed,
so let's include the local soc.h in plat/cpu.h and for drivers
still including plat/cpu.h.

Once the drivers are fixed not to include plat/cpu.h, we
can remove the file.

This is needed for the ARM common zImage support.

1243163494 ARM: kirkwood: fix buttons on lsxl boards
Change event type to switch for the power and autopower switches.
Additionally, this patch aligns the keycodes with the other linkstation
boards already supported by linux.

user can decide what if the platform is supposed to execute full power

07c9249f1f ARM: 7554/1: VIC: use irq_domain_add_simple()
Instead of allocating descriptors on-the-fly for the device tree
initialization case, use irq_domain_add_simple() which will take
care of this if you pass negative as the first_irq.

Alter the signature of __vic_init() to pass the first_irq as
signed so this works as expected.

Switching the VIC to use irq_domain_add_simple() also has the
upside of displaying the same WARNING when you boot with
pre-allocated descriptors on systems using SPARSE_IRQ but
yet not using device tree.

871df85a59 ARM: 7544/1: Add BUG_ON when hlt counter is wrongly used
1. On ARM platform, "nohlt" can be used to prevent core from idle
   process, returning immediately.
2. There are two interfaces, exported for other modules, named
   "disable_hlt" and "enable_hlt" are used to enable/disable the
   cpuidle mechanism by increasing/decreasing "hlt_counter".
   Disable_hlt and enable_hlt are paired operation,
   when you first call disable_hlt and then enable_hlt, the
   semantics are right.
3. There is no obvious constraint to prevent user(driver/module)
   code to prevent the case that enable_hlt is ahead of disable_hlt,
   which is a fatal operation on kernel state change from user,
   and there is no any WARNING or notification if the case happens
   in current kernel code.
   This patch aims to report BUG when the case happens, just like
   what the kernel do when enable_irq is ahead of disable_irq.

3581fe0ef3 ARM: 7556/1: perf: fix updated event period in response to PERF_EVENT_IOC_PERIOD
The PERF_EVENT_IOC_PERIOD ioctl command can be used to change the
sample period of a running perf_event. Consequently, when calculating
the next event period, the new period will only be considered after the
previous one has overflowed.

This patch changes the calculation of the remaining event ticks so that
they are offset if the period has changed.

153cd8e839 ARM: 7553/1: proc-v7: Ensure correct instruction set after cpu_reset
Because mov pc,<Rn> never switches instruction set when executed in
Thumb code, Thumb-2 kernels will silently execute the target code
after cpu_reset as Thumb code, even if the passed code pointer
denotes ARM (bit 0 clear).

This patch uses bx instead, ensuring the correct instruction set
for the target code.

Thumb code in the kernel is not supported prior to ARMv7, so other
CPUs are not affected.
