[PATCH 0/2] KVM: PPC: Book3S PR: SCV fixes

These patches seem to be the quickest and easiest way to avoid the
host crash and to get recent Linux images (that use scv) to run under
PR.

These are independent of the syscall emulation series. Those just came
about when looking at ways to fix the host problem and seeing emulation
was broken.

Thanks,
Nick
