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

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?
