[Xen-devel] [PATCH v3 13/24] vixen: Use SCHEDOP_shutdown to shutdown the machine

[Anthony Liguori <aliguori@xxxxxxxx>]

From: Jan H. Schönherr <jschoenh@xxxxxxxxx>

While the hwdom_shutdown() is able to reboot the system, it fails to
properly power it off. With SCHEDOP_shutdown, we delegate the problem.
