Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.12-20171215' into staging

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
