I'm a bit concerned with patches 4 and 7. It is hard to map the removals
and additions and there are some changes that looks like changing behaviors,
but end up not being clear in the big patch. Also with big patch it is prune
to the rebasing and backport conflicts.

Would be possible to split some work in moving individual functions from i915
to drm little by little with smaller patches?

But thank you for this great work. It is also good to align our drm drivers.

Thanks,
Rodrigo.
