Hi all,

I've finally been able to get back to this again, and I think it is now
hopefully ready to go. Changes from v3 are quite minor - basically a few
cosmetics and small tweaks (where I've taken the liberty of keeping
Baolu and Jason's review tags; hope that's OK!), the one functional
thing around blocking domains fixed, and plenty of reshuffling from
rebases. I'm happy to see that the IOMMUFD selftest problem has resolved
itself in the meantime, and it might even be able to use the standard
registration flow after this, however I'll leave that for someone else
more motivated, since my follow-up priority will be moving the of_xlate
business around at the bus level to sort out the probe_device ordering
mess once and for all.

Thanks,
Robin.
