Question about rtc_lock

The file arch/i386/kernel/bootflag.c contains this:

-------------------------------------------------
static void __init sbf_write(u8 v)
{
if(sbf_port != -1)
{
v &= ~(1<<7);
if(!parity(v))
v|=1<<7;

spin_lock(&rtc_lock);
CMOS_WRITE(v, sbf_port);
spin_unlock(&rtc_lock);
}
}
--------------------------------------------------

Does this code run with irqs disabled, or should these
spinlocks be _irq ?
