 *      Mask of allowable interrupts.
 *
 *      For IBM-AT machines, irqs 3, 4, 5, 7, 9, 10, 11, 12, 14, 15 are
 *      allowed.  Nearly all IBM-AT machines with pcic cards or bridges
 *      wire these interrupts (or a subset thereof) to the corresponding
 *      pins on the ISA bus.  Some older laptops are reported to not route
 *      all the interrupt pins to the bus because the designers knew that
 *      some would conflict with builtin devices.  Older versions of Windows
 *      NT had a special device that would probe for conflicts early in the
 *      boot process and formulate a mapping table.  Maybe we should do
 *      something similar.
 *
 *      For NEC PC-98 machines, irq 3, 5, 6, 9, 10, 11, 12, 13 are allowed.
 *      These correspond to the C-BUS signals INT 0, 1, 2, 3, 41, 42, 5, 6
 *      respectively.
 *
 *      Hiroshi TSUKADA-san writes in FreeBSD98-testers that CBUS INT 2
 *      (mapped to IRQ 6) is routed to the IRQ 7 pin of the pcic in pc98
 *      cbus add-in cards.  He has confirmed this routing with a visual
 *      inspection of his card or a VOM.
