I agree, it should be solvable, and much smaller and simpler than this
whole large chunk of "subsystem+driver" code. But I'm not the one
having to do this work, and it provides a bunch of easy cleanups for
people looking to get into kernel development, so I don't mind :)

But the "maintainers" should keep this in mind, as it is, this code is
_not_ acceptable for the main kernel tree because of the UIO framework
already present.
