For anything self-contained in gvt directory only, we can make a choice.

I think the patches that concern vgpu, have most often been around the GT
related code (opposed to display and PM).

That kind of makes me think we would get away with least amount of topic
branches and backmerges in the future if we also merged gvt-next to
drm-intel-gt-next. Thoughts?

That'd just mean a shift in timeline to send gvt-next latest early in -rc4
week.
