How about this:

arch/m68k/mac/psc.c

/*
* Try to kill all DMA channels on the PSC. Not sure how this his
* supposed to work; this is code lifted from macmace.c and then
* expanded to cover what I think are the other 7 channels.
*/

void psc_dma_die_die_die(void)
{
int i;

printk("Killing all PSC DMA channels...");
for (i = 0 ; i < 9 ; i++) {
psc_write_word(PSC_CTL_BASE + (i << 4), 0x8800);
psc_write_word(PSC_CTL_BASE + (i << 4), 0x1000);
psc_write_word(PSC_CMD_BASE + (i << 5), 0x1100);
psc_write_word(PSC_CMD_BASE + (i << 5) + 0x10, 0x1100);
}
printk("done!\n");
}
