I'm completely re-factoring the numatune parsing code and reworking
few other things for this patch.  For memory-file, that will be
automatically supported as well, but with Michal's patches.  We
already have an option that says "use hugepages" and we would like to
re-use that instead of creating new device(s).

But we will greatly value your input on these patches (both mine and
Michal's) when these hit the list.  So if there's something else you
find missing or wrong, that should be added or fixed, let me know.
