Changes since v5:
 * Split 1/3 from v5 into two commits, as suggestem by Gautham.
   1/4 splits wait_play_dead into mwait_play_dead_with_hint.
   2/4 and 3/4 uses the new mwait_play_dead_with_hint
   4/4 removes mwait_play_dead and calls cpuidle_play_dead right away

 * Reword 1-3/4 changelog slightly.

 * Move changelog from v5 1/3 into v6 4/4

Patryk Wlazlyn (4):
  x86/smp: Allow calling mwait_play_dead with an arbitrary hint
  ACPI: processor_idle: Add FFH state handling
  intel_idle: Provide the default enter_dead() handler
  x86/smp native_play_dead: Prefer cpuidle_play_dead() over
    mwait_play_dead()
