21 * The interrupt numbering scheme is defined in the

23 *
24 * Interrupts 0-15 are IPI
25 * 16-28 are reserved
26 * 29-31 are local. We allow 30 to be used for the watchdog.
27 * 32-1020 are global
28 * 1021-1022 are reserved
29 * 1023 is "spurious" (no interrupt)
30 *
31 * For now, we ignore all local interrupts so only return an interrupt if it's
32 * between 30 and 1020. The test_for_ipi routine below will pick up on IPIs.
33 *
34 * A simple read from the controller will tell us the number of the highest
35 * priority enabled interrupt. We then just need to check whether it is in the
36 * valid range for an IRQ (30-1020 inclusive).
