Well, in this case RFC was more a flag that I don't consider these
patches ready to merge right away.  But sure, I'll take encouragement.

Well.. the potential for conflicts with outstanding patches worries me
a bit, but I definitely want to go ahead with this some time pretty
soon.

Right, I'm only looking at target/ppc in this series, since that's
where I've most encountered the problems.  The spapr code in hw/ppc is
mostly style compliant already.  The other machines are a mixed bag,
but I think they're mostly better than target/ppc at any rate.
