I guess we can now re-do this series against 7.1-devel (qemu/master) which does
have the machine compat changes. Apart from that this should be ready now?
Yes, I think so. I can respin with the proper compat changes if requested.
FWIW, I played with the series a little bit, and did not spot any obvious
problems anymore, so feel free to add:

If you send a v6 with the compat stuff fixed, I can queue it for my next
s390x pull request.
