David, I don't see the unplug patch in your tree, intentional ?

Also I am working on supporting the CPU compat settings with the following
semantics:

-cpu host,power7 -device host-spapr-cpu-core,compat-cpu=power7

Whatever CPU compat level that is specifed with -cpu host is considered
as base and the compat-cpu property specified with -device will be
validated against the base compat level. And this property 'compat-cpu'
will be supported only for host-spapr-cpu-core type.

Is this semantics fine ?

Bharata.
