[Xen-devel] [PATCH] mini-os: drop shutdown variables when CONFIG_XENBUS=n

[Samuel Thibault <samuel.thibault@xxxxxxxxxxxx>]

Shutdown variables are meaningless when CONFIG_XENBUS=n since no
shutdown event will ever happen.  Better make sure that no code tries to
use it and never get the hoped shutdown event.
