This branch contains platform updates for 3.10. Among the highlights:
 
 - Support for the new Atmel Cortex-A5 based platforms (SAMA5D3)
 - New support for CSR SiRFatlas6 SoCs
 - A handful of updates for NVidia T114 (a.k.a. Tegra 4)
 - A bunch of updates for the shmobile platforms
 - A handful of updates for davinci
 - A few updates for Qualcomm MSM
 - Plus a handful of other patches, defconfig updates, etc.

554c06ba3e cpuidle: remove en_core_tk_irqen flag
The en_core_tk_irqen flag is set in all the cpuidle driver which
means it is not necessary to specify this flag.

Remove the flag and the code related to it.

5db9f43621 ARM: EXYNOS: handle properly the return values
The cpuidle_register_driver return value is not checked.
The init function returns always -EIO when cpuidle_register_device
fails but the error could be different.

This patch fixes that by checking the cpuidle_register_driver properly
and returning the correct value when cpuidle_register_device fails.

6a57d104c8 ARM: arm-soc: SoC updates, take 2
This is the second batch of SoC updates for the 3.8 merge window,
 containing parts that had dependencies on earlier branches such that we
 couldn't include them with the first branch.
 
 These are general updates for Samsung Exynos, Renesas/shmobile and a
 topic branch that adds SMP support to Altera's socfpga platform.

830145796a ARM: EXYNOS: Add ARCH_EXYNOS and reorganize arch/arm/mach-exynos
The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.

This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.
