[Intel-gfx] [PATCH 0/9] rps locking fixes

[Daniel Vetter]

Hi all

While reviewing Chris' simplified mark_busy/idle code I've noticed that we
seriously lack some locking. This series here fixes the first part around the
gpu power handling, the pll up/downclocking might still be rather broken :(

Since this clearly fixes some issues with the code, also try another stab at
enabling rc6 on ilk by default.

Review, flames and comments highly welcome!

Cheers, Daniel
