Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-4.0-20190219' into staging

ppc patch queue 2019-02-19

Here's the next batch of ppc and spapr patches.  Higlights are:

 * A bunch of improvements to TCG handling of vector instructions from
   Richard Henderson and Marc Cave-Ayland

 * Cleanup to the XICS interrupt controller from Greg Kurz, removing
   the special KVM subclasses which were a bad idea

 * Some refinements to the XIVE interrupt controller from Cédric Le
   Goater

 * Fix from Fabiano Rosas for a really dumb buffer overflow in the
   device tree code for memory hotplug

 * Code for allowing access to SPRs from the gdb stub from Fabiano
   Rosas

 * Assorted minor fixes and cleanups
