5 * This should be the same as the max(NUM_X_SOURCES) for all the
6 * different m68k hosts compiled into the kernel.
7 * Currently the Atari has 72 and the Amiga 24, but if both are
8 * supported in the kernel it is better to make room for 72.
9 * With EtherNAT add-on card on Atari, the highest interrupt
10 * number is 140 so NR_IRQS needs to be 141.

36 * Interrupt source definitions
37 * General interrupt sources are the level 1-7.
38 * Adding an interrupt service routine for one of these sources
39 * results in the addition of that routine to a chain of routines.
40 * Each one is called in succession. Each individual interrupt
41 * service routine should determine if the device associated with
42 * that routine requires service.
