The dependent fix has already been queued for 4.17 as commit 702791f7f204
("drm/i915: add schedule out notification of preempted but completed request"),
and before we could revert previous workaround, we had a regression issue which
was later resolved, so this revert was delayed for regression verification and
validation. And now it has passed our full testing, so I consider to push it for
4.17 instead of still keeping previous workaround...

yeah, sorry, that's missed. Will fix that against workaround commit and re-send
this pull. Will that be fine for you?
