Note for later: Move this to some lib/ file, this is not epia-cn
specific in any way.

Empty file? Drop? At least until it's actually needed (if it ever is).

I doubt that someone at AMD wrote any of this code in 2007. Please don't
carry around (C) lines for any such trivial files where almost nothing
(if anything at all) if from the copyright holder you're listing...

(it _is_ important to keep the (C) lines when you copy/reuse a
non-trivial amount of non-trivial code, of course!)

Just
  Copyright (C) 2008 Ronald G. Minnich <rminnich at gmail.com>
is fully sufficient here, IMO.
