2013-02-05pinctrl: exynos: change PINCTRL_EXYNOS optionKukjin Kim
Since pinctrl-exynos can support exynos4 and exynos5 so changed the option name to PINCTRL_EXYNOS for more clarity.

Pull ARM fixes from Russell King: "A number of fixes: Patrik found a problem with preempt counting in the VFP assembly functions which can cause the preempt count to be upset. Nicolas fixed a problem with the parsing of the DT when it straddles a 1MB boundary. Subhash Jadavani reported a problem with sparsemem and our highmem support for cache maintanence for DMA areas, and TI found a bug in their strongly ordered memory mapping type. Also, three fixes by way of Will Deacon's tree from Dave Martin for instruction compatibility and Marc Zyngier to fix hypervisor boot mode issues." * 'fixes' of git://git.linaro.org/people/rmk/linux-arm: ARM: 7629/1: mm: Fix missing XN flag for for MT_MEMORY_SO ARM: DMA: Fix struct page iterator in dma_cache_maint() to work with sparsemem ARM: 7628/1: head.S: map one extra section for the ATAG/DTB area ARM: 7627/1: Predicate preempt logic on PREEMP_COUNT not PREEMPT alone ARM: virt: simplify __hyp_stub_install epilog ARM: virt: boot secondary CPUs through the right entry point ARM: virt: Avoid bx instruction for compatibility with <=ARMv4

During the migration to the common clock framework, calls to the functions omap2xxx_clkt_vps_late_init() were not preserved for OMAP2420 and OMAP2430. This causes the variables "sys_ck_rate" and "curr_prcm_set" to be uninitialised on boot. On reboot, this causes the following error message to be displayed because the appropriate MPU clock frequency (derived from sys_ck_rate) cannot be found. "Could not set MPU rate to 4294MHz" Fix this by adding back calls to omap2xxx_clkt_vps_late_init() in the OMAP2420 and OMAP2430 clock initialisation code.

2013-01-16ARM: 7628/1: head.S: map one extra section for the ATAG/DTB areaNicolas Pitre
We currently use a temporary 1MB section aligned to a 1MB boundary for mapping the provided device tree until the final page table is created. However, if the device tree happens to cross that 1MB boundary, the end of it remains unmapped and the kernel crashes when it attempts to access it. Given no restriction on the location of that DTB, it could end up with only a few bytes mapped at the end of a section. Solve this issue by mapping two consecutive sections.

2013-01-16ARM: 7627/1: Predicate preempt logic on PREEMP_COUNT not PREEMPT aloneStephen Boyd
Patrik Kluba reports that the preempt count becomes invalid due to the preempt_enable() call being unbalanced with a preempt_disable() call in the vfp assembly routines. This happens because preempt_enable() and preempt_disable() update preempt counts under PREEMPT_COUNT=y but the vfp assembly routines do so under PREEMPT=y. In a configuration where PREEMPT=n and DEBUG_ATOMIC_SLEEP=y, PREEMPT_COUNT=y and so the preempt_enable() call in VFP_bounce() keeps subtracting from the preempt count until it goes negative. Fix this by always using PREEMPT_COUNT to decided when to update preempt counts in the ARM assembly code.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: atmel: Fixes for pinctrl Due to a series of problems with the handling of Atmel, a combination of making changes that make other branches instantly buggy and a general failure to deal with the resulting issues effectively, v3.8 Atmel audio currently won't work at all for DT boards without adding pinctrl definitions and a request for those.

2013-01-14ARM: imx: correct low-power mode settingShawn Guo
The hardware reset value of bit CCM_CLPCR_LPM enables WAIT mode (WAIT_UNCLOCKED) by default. However this is undesirable because WAIT mode should only be enabled when there is a driver managing ARM clock gating. Correct the initial power mode to WAIT_CLOCKED (disable WAIT mode). While at it, the power mode after resuming is also set back to WAIT_CLOCKED from STOP_POWER_OFF. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-01-14ARM: imx: disable cpu in .cpu_kill hookShawn Guo
It's buggy to disable the cpu that is being hot-unplugged in .cpu_die hook which runs on the cpu itself. Instead, it should be done in .cpu_kill which runs on the thread (another cpu) that asks for shutting down the cpu. Move imx_enable_cpu(cpu, false) call into .cpu_kill hook, and leave the cpu to be hot-unplugged in WFI within .cpu_die, so that we can get a more stable cpu hot-plug operation.

2013-01-14ARM: dts: prevent *.dtb from always being rebuiltStephen Warren
if_changed (used by the *.dts->*.dtc rule) rebuilds files if they aren't contained in $(targets). (make V=2 indicates this). Add $(dtb-y) to $(targets) to prevent *.dtb from always being rebuilt. This fixes a regression introduced by the .dtb rule rework in 499cd82 "ARM: dt: change .dtb build rules to build in dts directory".

2013-01-11arm: mvebu: Fix compile for multiplatform when ARMv6 is selectedTony Lindgren
Some systems compile in both ARMv6 and ARMv7 into multiplatform configurations. This means the default compiler flags are for ARMv6, and we will get: arch/arm/mach-mvebu/coherency_ll.S: Assembler messages: arch/arm/mach-mvebu/coherency_ll.S:45: Error: selected processor does not support `dsb' Fix this by specifying ARMv7 flags for coherency_ll.o.
