Looks good to me. For patches 1-6:
Acked-by: Michael S. Tsirkin <mst@redhat.com>

For patch 7 - I'm not sure we want to ship qemu
that only supplies the MADT but not the other tables. So maybe we can
merge it disabling the functionality temporarily, until the rest of the
tables are converted?  A config flag will do.
