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 ?
