[Intel-gfx] [PATCH 04/14] drm/i915/guc: Initialize GuC before restarting engines

> Now that we're handling request resubmission the same way as regular
> submission (from the tasklet), we can move GuC initialization earlier,
> before restarting the engines. This way, we're no longer being in the
> state of flux during engine restart - we're already in user requested
> submission mode.

I've picked this one for dinq, any others you feel are not part of
preemption per-se and would like to push ahead of the main series?
Though it looks like preemption is robust, so maybe there won't be much
of a delay now?
