* 'for-linus' of git://ftp.arm.linux.org.uk/pub/linux/arm/kernel/git-cur/linux-2.6-arm: (207 commits) ARM: 7267/1: Remove BUILD_BUG_ON from asm/bug.h ARM: 7269/1: mach-sa1100: fix sched_clock breakage ARM: 7198/1: arm/imx6: add restart support for imx6q ARM: restart: remove the now empty arch_reset() ARM: restart: remove comments about adding code to arch_reset() ARM: restart: lpc32xx & u300: remove unnecessary printk ARM: restart: plat-samsung: remove plat/reset.h and s5p_reset_hook ARM: restart: w90x900: use new restart hook ARM: restart: Versatile Express: use new restart hook ARM: restart: versatile: use new restart hook ARM: restart: u300: use new restart hook ARM: restart: tegra: use new restart hook ARM: restart: spear: use new restart hook ARM: restart: shark: use new restart hook ARM: restart: sa1100: use new restart hook ARM: 7252/1: restart: S5PV210: use new restart hook ARM: 7251/1: restart: S5PC100: use new restart hook ARM: 7250/1: restart: S5P64X0: use new restart hook ARM: 7266/1: restart: S3C64XX: use new restart hook ARM: 7265/1: restart: S3C24XX: use new restart hook ... Fix up trivial conflict in arch/arm/mm/init.c due to removal of memblock_init() clashing with the movement of the sorting of the meminfo array.
