Merge branch 'powernv-cpuidle' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc

Pull powerpc non-virtualized cpuidle from Ben Herrenschmidt:
 "This is the branch I mentioned in my other pull request which contains
  our improved cpuidle support for the "powernv" platform
  (non-virtualized).

  It adds support for the "fast sleep" feature of the processor which
  provides higher power savings than our usual "nap" mode but at the
  cost of losing the timers while asleep, and thus exploits the new
  timer broadcast framework to work around that limitation.

  It's based on a tip timer tree that you seem to have already merged"
