- *     Interrupt routines for cpci.  Interrupt numbers are assigned from
- *     CPCI_IRQ_BASE to CPCI_IRQ_BASE+8 (8 interrupt sources).
- *
- * Note that the high-level software will need to be careful about using
- * these interrupts.  If this board is asserting a cPCI interrupt, it will
- * also see the asserted interrupt.  Care must be taken to avoid an
- * interrupt flood.
