That's going to create problems for us for weeks to come. I'm actually
tempted to ask Joonas or Tvrtko to just force push that out of there.

Only use drm-intel-gt-next for stuff that's specifically about gt or
gem, and touches files used by gt or gem only. For everything else, use
drm-intel-next. When in doubt, err on the side of drm-intel-next.

It's not enough that one of the patches changes parameters of
for_each_gt() macro.

We can cross-merge drm-intel-next to drm-intel-gt-next, but we can't
cross-merge drm-intel-gt-next to drm-intel-next. This means the only way
to sync those i915_drv.h changes to drm-intel-next is to have a
drm-intel-gt-next pull request merged to drm-next, and then backmerged
to drm-intel-next. That's not going to happen for several weeks.

Any change aimed at drm-intel-next that conflicts with the i915_drv.h
changes will now be pending on those merges.

BR,
Jani.
