Merge tag 'kvm-ppc-next-5.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc into HEAD
KVM PPC update for 5.5
* Add capability to tell userspace whether we can single-step the guest.
* Improve the allocation of XIVE virtual processor IDs, to reduce the
risk of running out of IDs when running many VMs on POWER9.
* Rewrite interrupt synthesis code to deliver interrupts in virtual
mode when appropriate.
* Minor cleanups and improvements.
