It would be useful to have some userfaultfd testcases in
tools/testing/selftests/.  Partly as an aid to arch maintainers when
enabling this.  And also as a standalone thing to give people a
practical way of exercising this interface.

What are your thoughts on enabling userfaultfd for other architectures,
btw?  Are there good use cases, are people working on it, etc?

Also, I assume a manpage is in the works?  Sooner rather than later
would be good - Michael's review of proposed kernel interfaces has
often been valuable.
