Merge remote-tracking branch 'dgibson/tags/ppc-for-2.8-20161123' into staging

ppc patch queue 2016-11-23

Here's the first set of 2.8 hard freeze bugfixes for ppc.

The biggest thing here is a batch of fixes for migration breakages in
both 2.7 and current 2.8.  Alas, there is at least one more migration
problem, which prevents memory unplug after a migration.  I hoped to
include a fix for that here, but it turned out to have some problems
bigger than those it was solving.  So, I expect at least one more hard
freeze pull request.

There are also a few other assorted bug fixes.
