Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.9-20170306' into staging

ppc patch queue for 2017-03-06

Looks like my previous batch wasn't quite the last before hard freeze.
This has a handful of bugfixes to go in.  They're all genuine
bugfixes, though not regressions in some cases.
