Hi,

This series adds initial KVM selftests support for powerpc
(64-bit, BookS). It spans 3 maintainers but it does not really
affect arch/powerpc, and it is well contained in selftests
code, just touches some makefiles and a tiny bit headers so
conflicts should be unlikely and trivial.

Hey Paolo and KVM group, if you didn't take the v1 series yet, could
you please take this instead. Otherwise I can send an incremental
fixup.

Since v1:
- r2 (TOC) was not being set for guest code
- MSR[VSX] was not being set for guest code
- Proper guest interrupt handling instead of quick hack that
  just made a ucall out to host.
- Adjust subject to better match kvm selftests convention.

Thanks,
Nick
