[Intel-gfx] [PATCH 0/9] PSR stability patches for HSW/BDW and VLV/CHV.

[Rodrigo Vivi]

Here goes my latest work on PSR for better stability.

Unfortunatelly I'm not enabling it by default yet because it still needs to be
intensivelly validated and there is one still pending flicker when I force link standby on
HSW & BDW.

Since I'm going to start the bug maintainance team now I'm sending this partial work that
I believe that is ready to be merged upstream right now.

The remaining issues will be fixed and it will be enabled soon.

Thanks,
Rodrigo.
