ppc patch queue for 2016-03-16 Accumulated patches for target-ppc, pseries machine type and related devices. As we are now in soft freeze, these are mostly fixes. * Fix KVM migration for several SPRs that qemu didn't handle * Clean up handling of SDR1, which allows a fix to the gdbstub * Fix a race in spapr_rng * Fix a bug with multifunction hotplug The exception is the 7 patches to allow EEH on spapr-pci-host-bridge devices (rather than the special and poorly designed spapr-vfio-pci-host-bridge device). I believe these are low risk of breaking non-EEH cases, and EEH cases were little used in practice previously (since libvirt did not support the special device amongst other things). It did have a draft posted before the soft freeze, removes a very ugly VFIO interface, and removes device we'd like to deprecate sooner rather than later. So, I'm hoping we can squeeze these in during the soft freeze. This includes two patches to the VFIO code, which Alex Williamson has indicated he's ok with coming through my tree.
