will likely have to rebase again.

Reviewing the diff, the changes are all well-isolated to hw/ppc + target-ppc,
with the following exceptions:
- trace-events
- a few additions to generic headers

Thank you. Awaiting FFe approval now. But looks like I may need to

Serge, we may want to pull them in and put in a PPA to see if IBM and
others can give the patchset a try. And ideally they'd report to
qemu-devel of their success/problems.

Seems like the upstream discussion is still unresolved in some areas
(and no patches are upstream in the git tree) and I don't understand
why.
I'm happy to pull these patches in now. Just as a sanity check,
@rharper - any definite badness that you see?
