This patch series makes the locking and synchronisation of the idle
code simpler and more correct. It fixes the occasional "cpu_idle_p9
called while pm disabled" message.

Since v1:
- Rebased on upstream.
- Reword some changelogs, add some more comments.


Nicholas Piggin (6):
  core/cpu: rewrite idle synchronisation
  core/cpu: remove POWER8 IPI loop
  core/cpu: refactor IPI sending
  core/cpu: move cpu_wake out of job_lock
  core/cpu: make cpu idle states simpler
  core/cpu: move sleep/wake synchronisation out from low level code
