I think this is basically ready for 2.10, once the kernel changes hit
master (they are queued in the s390 tree).

It's probably best to take this through my tree (pending acks of the
vfio parts from Alex W.). It probably also would be good to add an s390
maintainer for  hw/vfio/ccw.c (I'd be willing to do that).

Could you please resend on top of git://github.com/cohuck/qemu s390-next
and add a MAINTAINERS patch as well?
