Maybe you're using a really old kernel.  In linux-2.4.4 it's in
arch/ppc/kernel/irq.c:

-- snip --
#if (defined(CONFIG_8xx) || defined(CONFIG_8260))
/* Name change so we can catch standard drivers that potentially mess up
 * the internal interrupt controller on 8xx and 8260.  Just bear with me,
 * I don't like this either and I am searching a better solution.  For
 * now, this is what I need. -- Dan
 */
#define request_irq	request_8xxirq

...
...
...

int request_irq(unsigned int irq, void (*handler)(int, void *, struct pt_regs *),
	unsigned long irqflags, const char * devname, void *dev_id)
{
--/snip --


I don't know why it was done like this....
