ppc patch queue 2017-08-23 This is identical to the pull request from yesterday (20180822), except that a bug in one patch is fixed so that it doesn't break TCG on a ppc host. Last minute ppc related fixes for qemu-2.10. I'm not sure if these are critical enough to prompt another rc, but I'm submitting them for consideration. First, is Cornelia's fix for 480bc11e6 which meant "make check" would always fail on a ppc host. Tracking that down delayed submission of the rest of these patches, sorry. The rest are all fairly important bugfixes for qemu crashes or guest behaviour regression on ppc. Patches 2-4 specifically are fixes for regressions from qemu-2.9, caused by the compatibility mode and hotplug handling cleanups for the pseries machine type.
