[PATCH 0/7] ppc: record-replay fixes and enablement |

Here is a series that gets ppc pseries and powernv machines into
better shape for record-replay, maybe for 8.2. It's likely got a
few deficiencies but it does run test cases and helped find bugs
in migration already. It requires previous decrementer fixes to
work well.
I think we can get away without patch 1 for 8.1, because we
inadvertently fixed regular (non-rr) migration of reservation
with commit 392d328abe753. But opinions welcome.
For record/replay and avocado test reviewers, I would mainly
be interested in opinions about patch 6. I tried not to affect
existing archs much.
Thanks,
Nick
