Chris Wilson c4de7b0ffd drm/i915: Implement w/a for sporadic read failures on waking from rc6 ... As a w/a to prevent reads sporadically returning 0, we need to wait for the GT thread to return to TC0 before proceeding to read the registers. v2: adapt for Haswell changes (Eugeni). v3: use wait_for_atomic_us for thread status polling. v3: *really* use wait_for_atomic for polling.
