ppc patch queue 2017-09-08

This is the first batch of ppc related patches for qemu-2.11, and it's
accumulated quite a few things.  Includes:

  * A cleanup to handling of ppc cpu models from Igor
  * First parts of fixes to handling of guest vs. host SMT modes from
    Sam Bobroff
  * Preliminary patches towards supporting the Sam460 board from
    Balaton Zoltan
  * Several fixes for hotplug logic
  * Assorted other fixes and cleanups
