Does timer_interrupt() (the top-half handler) run with interrupts disabled?

[David Wuertele <dave-gnus@bfnet.com>]

My MIPS code's timer_interrupt() (the top-half handler) does not
explicitly disable interrupts.  timer_interrupt() is dispatched by
arch/mips/kernel/time.c:timer_irqaction:

static struct irqaction timer_irqaction = {
	timer_interrupt,
	SA_INTERRUPT,
	0,
	"timer",
	NULL,
	NULL
};

I'm trying to figure out whether the calling function disables
interrupts.  Any suggestions?

Dave
