[PATCH 0/4] xen, usb: support pvUSB drivers

[Juergen Gross <jgross@suse.com>]

This series adds XEN pvUSB support. With pvUSB it is possible to use physical
USB 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 pvUSB implementation done
for Linux 2.6 in 2008 by Fujitsu.

Normal operation of USB devices by adding and removing them dynamically to/from
a domain has been tested using various USB devices (USB 1.1, 2.0 and 3.0).
Assignment of a USB device at domain creation via config file has been tested
as well.

Tests have been performed with the xm toolset and with xl using patches
from Chun Yan Liu which are not upstream yet.
