drm/i915/bdw: The TLB invalidation mechanism has been removed from INSTPM While wandering in the spec, I noticed that BDW removes those 2 bits from INSTPM. I couldn't find any direct way to invalidate the TLB (ie without the ring working already). Maybe someone will be more lucky. At least, we now know we may be a problem.
