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

Pull non-critical ARM soc bug fixes from Olof Johansson:
 "These were submitted as bug fixes before v3.6 but not considered
  important enough to be included in it.  Some of them cross over to
  cleanup territory as well, and aren't strictly bugfixes."
