Hi Dave & Daniel,
Two important user visible fixes; GPU hang on BDW/SKL when idling
and top of screen corruption on GLK+ when FBC enabled.
Fix to Tigerlake perf/OA, HDCP commit computation touching global
state.
Then two CI spotted corner cases, race condition about context
retirement and lockdep splat about irqstate.
I'll send a PR next week still before holidays.
Regards, Joonas
