There's no rush, I don't think this will make it into v4.4 anyhow, as
we're already on -rc4 and there's a bunch of other stuff in flight, and
I haven't configured a way to test these patches yet.

Speaking of which, does the QEMU side of this patch set require first
adding the GICv3 emulation for the data structures or is there a
stand-alone migration patch set somewhere?
