[PULL] drm-intel-fixes

[Joonas Lahtinen]

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
