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"

powerpc: Split timer_interrupt() into timer handling and interrupt handling routines
powerpc: Implement tick broadcast IPI as a fixed IPI message
powerpc: Free up the slot of PPC_MSG_CALL_FUNC_SINGLE IPI message
