Hi Eddie --

The delivery_mask was something that came from vBlades,
where devices could be partitioned. Much of this code was added
to Xen/ia64 before Xen 2.0, when it was
not clear what device support would be in Xen itself.

IRQ 0x30 was enabled to allow keyboard input to go through
to all the domains.  With Xen's console design, this can
probably go away.
