-/* The CPM2 internal interrupt controller.  It is usually
- * the only interrupt controller.
- * There are two 32-bit registers (high/low) for up to 64
- * possible interrupts.
- *
- * Now, the fun starts.....Interrupt Numbers DO NOT MAP
- * in a simple arithmetic fashion to mask or pending registers.
- * That is, interrupt 4 does not map to bit position 4.
- * We create two tables, indexed by vector number, to indicate
- * which register to use and which bit in the register to use.
