Subject: Re: [PATCH 02/29] drm/i915/gvt: integrate into the main Makefile

The thinking behind the split is to avoid any merge conflicts as the
gvt/ subdirectory is handled through separate pull request flow and
are note part of drm-tip.

The other subdirectories are part of drm-intel-next/drm-intel-gt-next
and are part of drm-tip.

So I would rather still see the Makefile live in gvt/ directory.
