Jani has the final word, but my understanding is that there will be no
more from i915 towards the 4.15 merge. Hmm, the origin of this timer,

    drm/i915/selftests: Wrap a timer into a i915_sw_fence

did make it into 4.15, so it would have been better to put into a
separate tree for the 4.15 merge window anyway. In hindsight, yes this
probably wants to be carried in the timer tree to be applied after i915.
(I guess there will be a few other stragglers that need to be converted
at the end of the merge window anyway.)

Jani?
