Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm 

Pull ARM fixes from Russell King:
 "A small number of fixes for stuff from the last merge window, and in
  one case (IRQ time accounting) the previous merge window."

* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:
  ARM: 7720/1: ARM v6/v7 cmpxchg64 shouldn't clear upper 32 bits of the old/new value
  ARM: 7715/1: MCPM: adapt to GIC changes after upstream merge
  ARM: 7714/1: mmc: mmci: Ensure return value of regulator_enable() is checked
  ARM: 7712/1: Remove trailing whitespace in arch/arm/Makefile
  ARM: 7711/1: dove: fix Dove cpu type from V7 to PJ4
  ARM: finally enable IRQ time accounting config
