Merge branch 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull NOHZ update from Thomas Gleixner: "Remove the call into the nohz idle code from the fake 'idle' thread in the powerclamp driver along with the export of those functions which was smuggeled in via the thermal tree. People have tried to hack around it in the nohz core code, but it just violates all rightful assumptions of that code about the only valid calling context (i.e. the proper idle task). The powerclamp trainwreck will still work, it just wont get the benefit of long idle sleeps" * 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: tick/powerclamp: Remove tick_nohz_idle abuse
