Linus Torvalds 820d41cf0c ARM: cleanups of io includes 
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.

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).
