/**

The above should explain why it's not _GPL right now. As far as
AutoNUMA is concerned I can drop the EXPORT_SYMBOL completely and not
allow modules to call this. In fact I could have coded this inside
autonuma too.

Ok. How about dropping it and then if its needed for modules then
export it out.

I can change it to _GPL, drop the EXPORT_SYMBOL or move it inside the
autonuma code, let me know what you prefer. If I hear nothing I won't
make changes.

Thanks,
Andrea
