[Intel-gfx] [PATCH 00/10] Haswell force wake/rps v3

[Eugeni Dodonov]

Hi,

Addressing bike color suggestions in the previous series:
 - simplify RPS function to reduce the number of changes. With this, we still
   write the RC6p/RC6pp bits, but those should be ignored on Haswell and
   experimental results have demonstrated no issues with it so far.
 - *really* use the wait_for_atomic for waiting
 - it is still possible (although unlikely) to use non-mt force wake on
   Haswell, so account for that as well.
 - split the rc6 enabling by default into a separate patch to help with
   bisection in the unthinkable case that rc6 will haunt our lives once again
 - move all those changes into intel_pm module to leave i915_drv cleaner
