[Xen-devel] [PATCH v2 19/23] vixen: Fix Vixen adaptation of send_global_virq()

[Anthony Liguori <aliguori@xxxxxxxx>]

From: Jan H. Schönherr <jschoenh@xxxxxxxxx>

The function originally did the following unconditionally:

   send_guest_global_virq(global_virq_handlers[virq] ?: hardware_domain, virq);

The new variant should reflect the non-Vixen case correctly.
