Normally this would go via the KVM/s390 or s390 tree (as Alex did
not want to handle s390 vfio devices).

Alex, as Jason is waiting for this to be in your tree could you take
this patch via your tree ?(please remove cc stable and Fixes for now
I want this to settle a bit).

To carry this patch in your tree with my kvm/s390 and s390 maintainer hat
