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).
