I read through the whole thing, and the only bit I didn't like
(drm_gem_shmem_create_with_handle returns an unrefcounted object
pointer) was a copy-and-paste from CMA that we should fix in both
places, and has no downside in the current usage since the pointer value
is unused. Just one question left:

I don't actually see this in the code. Wasn't there supposed to be a:
vma->vm_page_prot = pgprot_writecombine(vm_get_page_prot(vma->vm_flags));
