Simon Farnsworth 4e5359cd05 drm/i915: Avoid pageflipping freeze when we miss the flip prepare interrupt ... When we miss the flip prepare interrupt, we never get into the software state needed to restart userspace, resulting in a freeze of a full-screen OpenGL application (such as a compositor). Work around this by checking DSPxSURF/DSPxBASE to see if the page flip has actually happened. If it has, do the work we would have done when the flip prepare interrupt comes in. Also, add debugfs information to tell us what's going on (based on the patch from Chris Wilson attached to bugs.fdo bug #29798).
