Hi all,

Another round at attempting to use shmem helpers for vgem and also getting
them to not use VM_MIXEDMAP. I found an igt which had some funky encoded
expectations, so now neeeds a cover letter to test intel-gfx-ci how to
test this.

I also noticed that etnaviv and tegra are also using VM_MIXEDMAP (aside
from ttm based drivers).

Test-with: 20210527140732.5762-1-daniel.vetter@ffwll.ch

Cheers, Daniel
