which irqflag to use with request_irq

hi,

When using the function:
int request_irq (unsigned int      irq,
     irq_handler_t      handler,
     unsigned long      irqflags,
     const char *      devname,
     void *      dev_id);

To connect an ISR to one of the processor's
peripherals irq (SCC in my case).

Which value I should use for irqflags,
from the list in: interrupt.h file.

Kernel 2.6.24
Processor: MPC8272

Thanks,
Liran.
