Paolo or Radim,

Please do a pull from my kvm-ppc-next-5.4-1 tag to get a PPC KVM
update for 5.4.  There is not a lot this time, mostly minor fixes and
some prep for future patch series, plus a series that fixes a race
condition in the XIVE interrupt controller code where interrupts could
arrive after free_irq() and cause hangs and crashes in the host.

The XIVE fix touches both PPC KVM and generic powerpc code, so Michael
Ellerman put it in his topic/ppc-kvm branch and I have merged that
branch into my kvm-ppc-next branch.

Thanks,
Paul.
