Subject[PATCH v2 1/6] xen: no need to delay xen_setup_shutdown_event for hvm guests anymore
Date
From: Stefano Stabellini <stefano.stabellini@eu.citrix.com>

Now that xenstore_ready is used correctly for PV on HVM guests too, we
don't need to delay the initialization of xen_setup_shutdown_event
anymore.
