Merge tag 'kvm-ppc-next-4.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc
PPC KVM update for 4.16 - Allow HPT guests to run on a radix host on POWER9 v2.2 CPUs without requiring the complex thread synchronization that earlier CPU versions required. - A series from Ben Herrenschmidt to improve the handling of escalation interrupts with the XIVE interrupt controller. - Provide for the decrementer register to be copied across on migration. - Various minor cleanups and bugfixes.
