Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.11-20171017' into staging

ppc patch queue 2017-10-17

Here's the currently accumulated set of ppc patches for qemu.

  * The biggest set here is the ppc parts of Igor Mammedov's cleanups
    to cpu model handling
  * The above also includes a generic patches which are required as
    prerequisites for the ppc parts.  They don't seem to have been
    merged by Eduardo yet, so I hope they're ok to include here.
  * Apart from that it's basically just assorted bug fixes and cleanups
