This turned out to be a bit of a trainwreck, mostly due to
the patches being merged hastily at the end of the merge window.
For this reason, there are a few bugs for intra-host migration
as well.
Compared to the v1 I posted last week, there's many more bugfixes,
and the code I promised to avoid dangling ASIDs when a VM has
mirrors and is migrated.
