Just an editor note: that's not really additional information compared
to the subject of the patch. Also subject message could be a bit more
direct and mention SKL:
drm/i915/skl: Implement WaDisablePartialInstShootdown
> v1: Dont add WaDisableThreadStallDopClockGating as not SKL WA. (Found by Damien Lespiau)
v2, v1 was the original patch. Commit messages should also be wrapped
like emails, so 90 chars is too long.
