    Merge branch 'kvm-ppc-next' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc into HEAD
    The main thing here is a new implementation of the in-kernel
    XICS interrupt controller emulation for POWER9 machines, from Ben
    POWER9 has a new interrupt controller called XIVE (eXternal Interrupt
    Virtualization Engine) which is able to deliver interrupts directly
    to guest virtual CPUs in hardware without hypervisor intervention.
    With this new code, the guest still sees the old XICS interface but
    performance is better because the XICS emulation in the host uses the
    XIVE directly rather than going through a XICS emulation in firmware.
