[PATCH 0/5] FWNMI follow up patches

Here's a bunch of other patches remaining  after the last round,
for some less critical issues. Take these before or after the 5.0
freeze as you like.

Patch 1 is the main thing I think should be considered as a fix:
without it, non-FWNMI guests under KVM see behaviour change with
the FWNMI feature. I kept it out of the "must have" round because
Linux has long been FWNMI capable (I don't know state of FreeBSD
though), and because I have not tested under KVM with hardware
MCE injection.

2-3 are hopefully quite harmless comments and messages.

Patch 4 helps the guest stay up under some QoS corner cases.
Lastly is a machine check injection monitor command which helps
test things, it may not be ready for merge but it's useful for
the series.

Patch 5 is monitor command to inject MCEs, it's a bit janky
but it works to test qemu and guests.

Nicholas Piggin (5):
  ppc/spapr: KVM FWNMI should not be enabled until guest requests it
  ppc/spapr: Improve FWNMI machine check delivery corner case comments
  ppc/spapr: Add FWNMI machine check delivery warnings
  ppc/spapr: Don't kill the guest if a recovered FWNMI machine check
    delivery fails
  target/ppc: Implement simple monitor mce injection
