[Skiboot] [PATCH v2 0/6] idle synchronisation improvements

[Nicholas Piggin]

This patch series makes the locking and synchronisation of the idle
code simpler and more correct. It fixes the occasional "cpu_idle_p9
called while pm disabled" message.

Since v1:
- Rebased on upstream.
- Reword some changelogs, add some more comments.

Thanks,
Nick
