[Intel-gfx] [PATCH 0/4] Re-enable RC6 on Ironlake

[Ben Widawsky]

There might be some further patches. I believe we may need to reinitialize rc6
after a GPU reset, but I don't know for certain yet.

Also it was recommended by Chris that we use i915_enable_rc6 for coarser
control over gen6 as well. That function was a little daunting, and so I'll
submit that as a separate patch when I have more time.
