This series is an attempt to fix many hang bugs we have at SNB with RC6. https://bugzilla.kernel.org/show_bug.cgi?id=43267 Reporter of this 43267 mentioned that one ugly patch of mine fixed his hangs. That patch was wrong and probably regressing some other stuff already fixed by Chris. At that patch there was also useless things like asking gpu to generate interrupts we don't process. So my guess is that some or all of these 3 patches are fixing actual bugs. Manly the second and third one.
