[Intel-gfx] [PATCH 0/2] drm/i915: Page flip vs. GPU reset fixes

[ville.syrjala at linux.intel.com]

Here are the (hopefully) final versions of the page flip vs. GPU reset fixes.

They survive the i-g-t kms_flip flip-vs-modeset-vs-hang and
flip-vs-panning-vs-hang tests, as well as stopping the rings while a
fullscreen GL application is running under X.

Now that we finish the page flips explicitly, the patches should also work
on Gen2-Gen4 hardware, assuming we have otherwise working GPU reset support
for them.
