* interrupt controller spec. To wit:

*
|
||||
* Interrupts 0-15 are IPI
|
||||
* 16-28 are reserved
|
||||
* 29-31 are local. We allow 30 to be used for the watchdog.

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