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" * 'powernv-cpuidle' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: cpuidle/powernv: Parse device tree to setup idle states cpuidle/powernv: Add "Fast-Sleep" CPU idle state powerpc/powernv: Add OPAL call to resync timebase on wakeup powerpc/powernv: Add context management for Fast Sleep 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
