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 ?
