  drivers/gpu/drm/i915/i915_gem.c: Add missing error handling code
  drm/i915: Don't mask the return code whilst relocating.
  drm/i915: If the GPU hangs twice within 5 seconds, declare it wedged.
  drm/i915: Only print 'generating error event' if we actually are
  drm/i915: Try to reset gen2 devices.
  drm/i915: Clear fence registers on GPU reset
  drm/i915: Force the domain to CPU on unbinding whilst wedged.
  drm: Move the GTT accounting to i915
