Ok, let's keep it simple. The only two things we need are:
1) remove the patch to disable is_dup_page
2) rename the transport to "x-rdma" (just in migration.c)
Both things together let us keep it safe for a release or two. Let's
merge this thing.
I would drop the chunk based thing too. Besides being slow, it turns
out that it pins all memory anyway. So no memory overcommit.
It doesn't pin zero pages. Those are never transmitted (it's a recent
change). So pages that are ballooned at the beginning of migration, and
remain ballooned throughout, will never be pinned.

Of course Michael says it's slow unless you disable zero page detection,
and then I'm guessing it does?
