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!
