Seem that git-s390 is currently carrying the old versions of these patches.

I'll drop git-s390.  Which will presumably kick off a cascade of droppages
due to git-s390 versus git-kvm damage control.  All of which will need to
be undropped in some fashion when those trees come to their senses.  Ho
hum.
