ppc patch queue 2019-02-04 Here's the next batch of ppc target and spapr related changes. Highlights are: * A number of endianness handling cleanups from Mark Cave-Ayland * Updated Mac VGA driver * Updated SLOF image * Some XIVE cleanups and small fixes * ppc4xx cleanups and fixes from BALATON Zoltan There are a few chances not technically in the ppc target code: * Several MAINTAINERS updates * Fixes for unmapping of hugepages on power hosts The latter is included because it's primarily of interest for ppc KVM setups.
