Paolo,

the power people have not used your branch yet. So you could - as an alternative also
create an kvm-cap-ppc-211 branch for 5.17 and leave the s390 cap at 210. But it would
be good to do something now so that we have final numbers for the caps. Either create
a kvm-cap-ppc-211 branch, or merge the kvm-cap-ppc-210 branch into next and fixup the
s390 cap to become 211.
