* 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.
