This patch series implements split core mode on POWER8.  This enables up to 4
subcores per core which can each independently run guests (per guest SPRs like
SDR1, LPIDR etc are replicated per subcore).  Lots more documentation on this
feature in the code and commit messages.

Most of this code is in the powernv platform but there's a couple of KVM
specific patches too.

Patch series authored by mpe and me with a few bug fixes from others.

v2:
   There are some minor updates based on comments and I've added the Acks by
   Paulus and Alex for the KVM code.

I don't see changelogs inside the individual patches. Please make sure to always mention what changed from one version to the next in a particular patch, so that I have the chance to check whether that change was good :).

Also, is there any performance penalty associated with split core mode? If not, could we just always default to split-by-4 on POWER8 bare metal?
