Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.7-20160527' into staging

ppc patch queue for 2016-05-27 (first pull for qemu-2.7)

I'm back from holidays now, and have re-collated the ppc patch queue.
This is a first pull request against the qemu-2.7 branch, mostly
consisting of patches which were posted before the 2.6 freeze, but
weren't suitable for late inclusion in the 2.6 branch.

 * Assorted bugfixes and cleanups
 * Some preliminary patches towards dynamic DMA windows and CPU hotplug
 * Significant performance impovement for the spapr-llan device
 * Added myself to MAINTAINERS for ppc (overdue)
