[PATCH 0/3] Keep device awake during GT TLB invalidations

[Matthew Brost]

Issue was raised in [1], attempt to fix this by holding PM ref when GT
TLB invalidations are in flight. An alternative solution could be hold a
PM ref when any H2G are inflight which expect a G2H.

Including two patches from [2] as they a prerequisite for this fix.
