The recent KVM work clashed with a couple of my patches, so they were reverted/dropped for this merge window.
I've made another attempt at them, hopefully done in a way that is more compatible with KVM requirements and in a bit nicer way (POWER8 contex switching should speed up a bit too). I'm not completely sure I got patch 2 right. It works on POWER8, but haven't been able to get POWER9 running with hash on radix.
