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
