Request IRQ Error

Hello,

I wrote a driver that has an interrupt requested by a timer. This
driver is working in the kernel downloaded at code.google.
Now, i downloaded the kernel from source.mvista.com (linux-omap-2.6)
but i am getting an error on compilation:

dmtimer.c:789: error: 'SA_INTERRUPT' undeclared (first use in this
function)

The error ocurr on the function "request_irq(INT_24XX_GPTIMER2,
timer2_isr, SA_INTERRUPT, "Timer 2",NULL)"

How can i fix it?

Regards!
