- * The CAT bus is a serial configuration and test bus. Its primary

- * diagnose error conditions when a system interrupt occurs. The low
- * level interface is fairly primitive, so most of this file consists

- *
- * The solution is a variant on the NCR lazy SPL design:
- *
- * 1) To disable an interrupt, do nothing (other than set the
- * IRQ_DISABLED flag). This dares the interrupt actually to arrive.
- *
- * 2) If the interrupt dares to come in, raise the local mask against
- * it (this will result in all the CPU masks being raised

- *
- * 3) To enable the interrupt, lower the mask on the local CPU and
