Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-3.0-20180612' into staging

ppc patch queue 2018-06-12

Here's another batch of ppc patches towards the 3.0 release.  There's
a fair bit here, because I've been working through my mail backlog
after a holiday.  There's not much of a central theme, amongst other
things we have:
    * ppc440 / sam460ex improvements
    * logging and error cleanups
    * 40p (PReP) bugfixes
    * Macintosh fixes and cleanups
    * Add emulation of the new POWER9 store-forwarding barrier
      instruction variant
    * Hotplug cleanups
