Hi, here's a fairly large s390x update for which I plan to send a pull request next week.
The biggest part is the introduction of the new vfio-ccw support to passthrough ccw devices (kernel part has been merged as of 4.12-rc1). There's also some changes to allow the ccw bios to boot from scsi generic devices, and a bugfix for initial reset.
