Merge tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull "ARM: cleanups of io includes" from Olof Johansson: "Rob Herring has done a sweeping change cleaning up all of the mach/io.h includes, moving some of the oft-repeated macros to a common location and removing a bunch of boiler plate. This is another step closer to a common zImage for multiple platforms." Fix up various fairly trivial conflicts (<mach/io.h> removal vs changes around it, tegra localtimer.o is *still* gone, yadda-yadda). * tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (29 commits) ARM: tegra: Include assembler.h in sleep.S to fix build break ARM: pxa: use common IOMEM definition ARM: dma-mapping: convert ARCH_HAS_DMA_SET_COHERENT_MASK to kconfig symbol ARM: __io abuse cleanup ARM: create a common IOMEM definition ARM: iop13xx: fix missing declaration of iop13xx_init_early ARM: fix ioremap/iounmap for !CONFIG_MMU ARM: kill off __mem_pci ARM: remove bunch of now unused mach/io.h files ARM: make mach/io.h include optional ARM: clps711x: remove unneeded include of mach/io.h ARM: dove: add explicit include of dove.h to addr-map.c ARM: at91: add explicit include of hardware.h to uncompressor ARM: ep93xx: clean-up mach/io.h ARM: tegra: clean-up mach/io.h ARM: orion5x: clean-up mach/io.h ARM: davinci: remove unneeded mach/io.h include [media] davinci: remove includes of mach/io.h ARM: OMAP: Remove remaining includes for mach/io.h ARM: msm: clean-up mach/io.h ...
