Daniel writes:
"Probably the last feature pull for 3.9, there's some fixes outstanding
thought that I'd like to sneak in. And maybe 3.8 takes a bit longer ...
Anyway, highlights of this pull:
- Kill the horrible IS_DISPLAYREG hack to handle the mmio offset movements
  on vlv, big thanks to Ville.
- Dynamic power well support for Haswell, shaves away a bit when only
  using the eDP port on pipe A (Paulo). Plus unclaimed register fixes
  uncovered by this.
- Clarifications of the gpu hang/reset state transitions, hopefully fixing
  a few spurious -EIO deaths in userspace.
- Haswell ELD fixes.
- Some more (pp)gtt cleanups from Ben.
- A few smaller things all over.

Plus all the stuff from the previous rather small pull request:
- Broadcast RBG improvements and reduced color range fixes from Ville.
- Ben is on a "kill legacy gtt code for good" spree, first pile of patches
  included.
- No-relocs and bo lut improvements for faster execbuf from Chris.
- Some refactorings from Imre."
