Subject: [PATCH v2 05/11] drm/i915/execlists: Distinguish the incomplete
context notifies
Let the listener know that the context we just scheduled out was not complete,
and will be scheduled back in at a later point.
v2: Handle CONTEXT_STATUS_PREEMPTED in gvt by aliasing it to CONTEXT_STATUS_OUT
for the moment, gvt can expand upon the difference later.
