16 /* The 8260 has an internal interrupt controller with a maximum of
17 * 64 IRQs. We will use NR_IRQs from above since it is large enough.
18 * Don't be confused by the 8260 documentation where they list an
19 * "interrupt number" and "interrupt vector". We are only interested
20 * in the interrupt vector. There are "reserved" holes where the
21 * vector number increases, but the interrupt number in the table does not.
22 * (Document errata updates have fixed this...make sure you have up to
23 * date processor documentation -- Dan).
