ppc patch queue 2017-12-15 

First pull request for qemu-2.12.  This has quite a bit of stuff
 accumulated while 2.11 was finalizing.  Highlights are:
 
   * Some preliminary work towards implementing the "XIVE" POWER9
     interrupt controller
   * Some fixes for problems during reboot with MTTCG
   * A substantial TCG performance improvement via
     tcg_get_lookup_and_goto_ptr
   * Numerous assorted cleanups and bugfixes that weren't urgent enough
     for 2.11
