No objections from my side, but the interesting code is outside my area.

I feel we (including myself) are abusing include/qom/cpu.h (here there's
not even a single CPUState argument) but I don't have a better
suggestion. At some point we'll need to revisit the cpu.h vs. cpu-all.h
etc. split or even introduce something new.

I'm preparing a qom-cpu pull and assume this will go through the
migration tree when finalized.

Regards,
Andreas
