Subject: [PATCH v2 0/3] SRF: Fix offline CPU preventing pc6 entry

Sending a tiny change in response to a suggestion I got off-list.

Changes since v1:
	* Remove explicit assignment to global, play_dead_mwait_hint as
	  suggested by Dave Hansen off-list, to prevent compiler from
	  moving it out of the .bss.

Patryk Wlazlyn (3):
  x86/smp: Move mwait hint computation out of mwait_play_dead
  x86/smp: Allow forcing the mwait hint for play dead loop
  intel_idle: Identify the deepest cstate for SRF
