I think the best way forward may be to adapt the pmap_helper.ko module
and extend it to return the result of its call to pmap_extract(), rather
than faking 'page cookies' as I have currently patched Exmap to do.
There's no way for it to learn precisely which pages are mapped and
resident for the same reason, and it really should.
I have to crack on with other work, I may get around to this later on.
