I have prepared $(qom-obj-twice-y) to allow for:

#ifdef CONFIG_SOFTMMU
    .parent = TYPE_DEVICE, // or TYPE_SYS_BUS_DEVICE
#else
    .parent = TYPE_OBJECT,
#endif

So far it was not needed. :)

So to clarify, this is pro CPUState?

Thanks.

The implied RFC is, are we okay with reusing "CPUState" this way? Or
does someone - last call! - have a better identifier name?

Getting this series merged either means coordinating the PULL with a
maintainer so that no merge conflicts arise in-flight, or having the
maintainer re-run the commit-creating script himself.
