These patches implement enough to boot a SMT powernv machine to Linux
and boot a SMP KVM guest inside that.

There are a few more SPRs that need to be done, and per-LPAR SPRs are
mostly not annotated yet so it can't run in 1LPAR mode. But it is
enough to run skiboot/Linux with SMT so I'll just post the minimal
patches for RFC because the concept isn't really different to add
more SPRs and things.

This is good material for 8.1. Please send a v1 and Cc: all pnv reviewers.

Thanks,

C.
