Now that I understand the problem, I do have a very simple (slightly
overkill) fix for paravirt patching. This can be cleaned up to avoid
the copies when they aren't needed, but that will take a little more
auditing of the various patchers. If you still prefer a revert I've
got one handy, and we can re-visit this all post .23.

This one avoids the patching when necessary, but needs some validation on
VMI (and Zach's not avail today). I'll resend when I know it's working
for all paravirt patchers.

Looks like it's already in -git. I tested with your fix and hit a different bug. Bisecting, will handle.
