Oh, very nice.

There's some risk here -- for example, vkms (with prime enabled, which
it doesn't currently) will fail badly at prime sharing buffers with
hardware drivers doing WC mappings of buffers.  But I guess we should be
preventing that at the kernel level when we enable prime, and having
userspace maybe test creating a shared resource when loading kmsro with
a particular backend.
