27 * The interrupt numbering scheme is defined in the
28 * interrupt controller spec. To wit:
29 *
30 * Interrupts 0-15 are IPI
31 * 16-28 are reserved
32 * 29-31 are local. We allow 30 to be used for the watchdog.
33 * 32-1020 are global
34 * 1021-1022 are reserved
35 * 1023 is "spurious" (no interrupt)
36 *
37 * For now, we ignore all local interrupts so only return an
38 * interrupt if it's between 30 and 1020. The test_for_ipi
39 * routine below will pick up on IPIs.
40 *
41 * A simple read from the controller will tell us the number
42 * of the highest priority enabled interrupt. We then just
43 * need to check whether it is in the valid range for an
44 * IRQ (30-1020 inclusive).
