Greg,
this is a backport of a patch that is needed to make
"KVM: s390: wire up bpb feature" useful in 4.4. Without that the
bpb feature is available but the guest does not know that it
can be used.

Some facility bits are in a range that is defined to be "ok for guests
without any necessary hypervisor changes". Enable those bits.

Indeed, this patch is needed, and it looks good to me.
