Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC fixes from Olof Johansson:
 "Again, a batch that's been sitting a couple of weeks, mostly because
  I anticipated a bit more material but it didn't show up -- which is
  good.

  These are all your garden variety fixes for ARM platforms.

  The most visible issue fixed here is probably the SMP reset issue on
  OMAP, the rest are minor stuff"
