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

Pull core ARM updates from Russell King:
 "This is the bulk of the core ARM updates for this merge window.
  Included in here is a different way to handle the VIVT cache flushing
  on context switch, which should allow scheduler folk to remove a
  special case in their core code.

  We have architectured timer support here, which is a set of timers
  specified by the ARM architecture for future SoCs.  So we should see
  less variability in timer design going forward.

  The last big thing here is my cleanup to the way we handle PCI across
  ARM, fixing some oddities in some platforms which hadn't realised
  there was a way to deal with their private data already built in to
  our PCI backend.

  I've also removed support for the ARMv3 architecture; it hasn't worked
  properly for years so it seems pointless to keep it around."
