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 ...
2012-03-13ARM: __io abuse cleanupRob Herring
Several platforms incorrectly use __io() for casting to 'void __iomem *'. This converts all of those uses to use the common IOMEM macro.

2012-01-23ARM: 7293/1: logical_cpu_map: decouple CPU mapping from SMPWill Deacon
It turns out that the logical CPU mapping is useful even when !CONFIG_SMP for manipulation of devices like interrupt and power controllers when running a UP kernel on a CPU other than 0. This can happen when kexecing a UP image from an SMP kernel. In the future, multi-cluster systems running AMP configurations will require something similar for mapping cluster IDs, so it makes sense to decouple this logic in preparation for this support.

2012-01-12ARM: mach-shmobile: r8a7779 SMP support V3Magnus Damm
This patch contains r8a7779 SMP support V3 - now including CPU hotplug offine and online support. The r8a7779 power domain code is tied together with SMP glue code which allows us to control the power domains via CPU hotplug. At this point the kernel boots with the 4 Cortex-A9 cores in SMP mode and all CPU cores except CPU0 can be hotplugged. The code in platsmp.c is quite far from pretty, but it is kept like that intentionally to avoid creating layers of code that will go away in the near future anyway. The code needs to be updated when some per-SoC handling code will be added to the ARM architecture, see the following patch for more information: "[RFC PATCH 0/3] Per SoC descriptor" Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
