Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.10-20170606' into staging

ppc patch queue 2017-06-06

Accumulated patches for ppc targets and the pseries machine type.

The big thing in this batch is a start on a substantial cleanup of the
pseries hotplug mechanisms, which were pretty confusing.  For now
these shouldn't cause substantial behavioural changes, but I am hoping
these lead to clearer code and eventually to fixes for the bugs we
have in hotplug handling, particularly when hotplug and migration are
combined.

The remaining patches are mostly bugfixes.
