Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.7-20160623' into staging
ppc patch queue for 2016-06-23
Currently outstanding patches for spapr, target-ppc and related
devices. This batch has:
* Significant new progress towards full support for hypervisor
mode
* Assorted bugfixes
* Some preliminary patches towards dynamic DMA window support
The last involves a change to memory.c, which Paolo has said I can
take through this tree.
