This series adds XEN pvSCSI support. With pvSCSI it is possible to use physical SCSI devices from a XEN domain. The support consists of a backend in the privileged Domain-0 doing the real I/O and a frontend in the unprivileged domU passing I/O-requests to the backend. The code is taken (and adapted) from the original pvSCSI implementation done for Linux 2.6 in 2008 by Fujitsu.
