I think we have a gap that after splitting the drm-intel-next pull requests into
two the drm-intel/for-linux-next branch is now missing material from
drm-intel/drm-intel-gt-next.

I think a simple course of action might be to start including drm-intel-gt-next
in linux-next, which would mean that we should update DIM tooling to add
extra branch "drm-intel/gt-for-linux-next" or so.

Which specific patches are missing in this case?
