ppc patch queue 2020-06-26 Here's another pull request for qemu-5.1. Not very much in this one, just a handful of assorted minor fixes and cleanups. I'm about to go on holiday for a couple of weeks, so this will be my last PR before the freeze, and maybe the last for 5.1 at all. If there's some super important fix we need, Greg Kurz will handle it.
