Great news! I have taken over Dean's xpmem patch set while he is on
sabbatical. Before he left, he had his patch mostly working on top of

test.

This is a patchset implementing MMU notifier callbacks based on Andrea's
earlier work. These are needed if Linux pages are referenced from something
else than tracked by the rmaps of the kernel (an external MMU).
