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....
