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"
