I don't have the hardware, and I don't see any good reason to make an
rdtsc cleanup depend on a more complicated driver change.  On the
other hand, if the maintainers want to clean it up, I think it would
be a great idea.

This really seems to be debugging code, though.  A normal kernel won't
even compile it.
