Subject: [PATCH] drm/i915: Fix retrieval of hangcheck stats
Git-commit: 4c9c0d09741deab0aac76b83961cfe95b24f3e6f
Patch-mainline: v4.13-rc1
References: FATE#322643 bsc#1055900
The default context is always supported (as it contains the global
hangcheck stats) and the contexts for hangcheck are not limited
to any ring.
This was dropped in 2013 because it was supposed to have been included
with Ben's full-ppgtt patch set. It never landed and the bug remains.
