From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
I set out to fix the pre-g4x GPU reset by protecting display commits with
an rw_semaphore. I originally went all out and added infrastructure to track
the committed state (as opposed the latest swapped state), but Daniel suggested
that we want to backport the thing so I simplified it to just use obj->state
instead. I will be posting the committed state handling as a followup as it
will also DTRT if/when we will start allowing queueing multiple commits per-crtc.
Not sure if we want to put the "committed" state stuf into the atomic helper or
I should just pull it all into i915. Suggestions welcome.
