Small update, after Gautham's review and few changes around comments that
referenced old mwait_play_dead code, that I noticed after submitting the
v6. Some places referenced the old mwait_play_dead() in the comments, so
I decided to reuse the mwait_play_dead() name, so that the comments
don't have to be updated.

Changes since v6:
 * Renamed mwait_play_dead to mwait_play_dead_cpuid_hint in 1/1, so that
   mwait_play_dead name can be reused for the function that takes the
   MWAIT hint as an argument. This leaves the comments around the
   smpboot.c file that reference the old mwait_play_dead() unchanged.

 * Moved the old comment above mwait_play_dead() to
   mwait_play_dead_with_hints in patch 4/4.

 * Added missing include of asm/smp.h in arch/x86/kernel/acpi/cstate.c

 * Removed empty line added by mistake, spotted by Gautham (Thanks!)
   in arch/x86/include/asm/smp.h

 * Reworded 1/4 commit message to better describe the changes the patch
   is actually making.

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()
