How does this relate to DRM/GEM? I don't understand too much about graphics
drivers, but it does sound like there is some overlap in functionality.

I guess at the very least the DMM should live in drivers/gpu/ instead of
drivers/misc, but perhaps it could be integrated more closely with the
existing code there.
