I'm not sure this is a good idea.  It isn't clear why any out of tree
driver would need to mess with the p2m (or that we would actually trust
a third party driver to do this correctly...).

Also, the general kernel policy is not to export symbols that aren't
used by something in the kernel tree itself.
