Merge branch 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King: "Changes included in this pull request: - revert pxa2xx-flash back to using ioremap_cached() and switch memremap() to use arch_memremap_wb() - remove pci=firmware command line argument handling - remove unnecessary arm_dma_set_mask() implementation, the generic implementation will do for ARM - removal of the ARM kallsyms "hack" to work around mode switching veneers and vectors located below PAGE_OFFSET - tidy up build system output a little - add L2 cache power management DT bindings - remove duplicated local_irq_disable() in reboot paths - handle AMBA primecell devices better at registration time with PM domains (needed for Samsung SoCs) - ARM specific preparation to support Keystone II kexec" * 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm: ARM: 8567/1: cache-uniphier: activate ways for secondary CPUs ARM: 8570/2: Documentation: devicetree: Add PL310 PM bindings ARM: 8569/1: pl2x0: Add OF control of cache power management ARM: 8568/1: reboot: remove duplicated local_irq_disable() ARM: 8566/1: drivers: amba: properly handle devices with power domains ARM: provide arm_has_idmap_alias() helper ARM: kexec: remove 512MB restriction on kexec crashdump ARM: provide improved virt_to_idmap() functionality ARM: kexec: fix crashkernel= handling ARM: 8557/1: specify install, zinstall, and uinstall as PHONY targets ARM: 8562/1: suppress "include/generated/mach-types.h is up to date."
