Merge branch 'depends/rmk/for-linus' into samsung/dt
Conflicts:
arch/arm/mach-exynos/Makefile
arch/arm/mach-exynos/cpu.c -> common.c
arch/arm/mach-exynos/include/mach/entry-macro.S
arch/arm/mach-exynos/init.c -> common.c
arch/arm/mach-s5p64x0/init.c -> common.c
arch/arm/mach-s5pv210/init.c -> common.c
Multiple files were moved into common.c files in the rmk/for-linus
branch, so this moves over the samsung/dt changes to the new
files.
