This adds nmi injection for pnv, and similar mce injection for spapr and pnv. The mce injection has already uncovered quite a few bugs in Linux papr guest and one in pnv host code, so it has been already very useful. The mambo simulator can do similar injection but it's a bit more clunky and needs to run KVM and QEMU in the sim to test papr guests, which is quite slow.
HMIs like timebase corruption would be another good candidate for error injection.
