2 * arch/m68k/atari/ataints.c -- Atari Linux interrupt handling code
6 * twiddled there and we won't get the right interrupts :-()
8 * Major change: The device-independent code in m68k/ints.c didn't know
9 * about non-autovec ints yet. It hardcoded the number of possible ints to
10 * 7 (IRQ1...IRQ7). But the Atari has lots of non-autovec ints! I made the

58 * --------------------------------
61 * <asm/atariints.h>): Autovector interrupts are 1..7, then follow ST-MFP,
62 * TT-MFP, SCC, and finally VME interrupts. Vector numbers for the latter can
