Hi,
Maybe I should not send patches this late at night as I end up messing things up and spamming sleeping people. Sorry for this version 4.
The real fix is in patch 2. The rest is a helper that adds the with_intel_gt_pm_if_awake() (from Chris) and one more check on the status of the engine before accessing it for clearing the TLB.
