Cool stuff.

Now we need to make sure that anyone who messes with vma code has run
the tests.  And has added more testcases, if appropriate.

Does it make sense to execute this test under selftests/ in some
fashion?  Quite a few people appear to be running the selftest code
regularly and it would be good to make them run this as well.

eep.  The best time for me to merge this is late in the -rc cycle so
the large skew between mainline and mm.git doesn't spend months
hampering ongoing development.  But that merge time is right now.
