Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.8-20160923' into staging

ppc patch queue 2016-09-23

This pull request supersedes ppc-for-2.8-20160922.  There was a clang
build error in that, and I've also added one extra patch in the new pull.

Included in this set of ppc and spapr patches are:
    * TCG implementations for more POWER9 instructions
    * Some preliminary XICS fixes in preparataion for the pnv machine type
    * A significant ADB (Macintosh kbd/mouse) cleanup
    * Some conversions to use trace instead of debug macros
    * Fixes to correctly handle global TLB flush synchronization in
      TCG.  This is already a bug, but it will have much more impact
      when we get MTTCG
    * Add more qtest testcases for Power
    * Some MAINTAINERS updates
    * Assorted bugfixes
    * Add the basics of NUMA associativity to the spapr PCI host bridge

This touches some test files and monitor.c which are technically
outside the ppc code, but coming through this tree because the changes
are primarily of interest to ppc.
