commit ca8efa1df1d15a1795a2da57f9f6aada6ed6b946 upstream.

This adds code to save the values of three SPRs (special-purpose
registers) used by userspace to control event-based branches (EBBs),
which are essentially interrupts that get delivered directly to
userspace.  These registers are loaded up with guest values when
entering the guest, and their values are saved when exiting the
guest, but we were not saving the host values and restoring them
before going back to userspace.

I already took this patch, right?

Yes, you did.  Thanks.

Paul.
