From asm/i386/kernel/traps.c (w/ the indents shrunk to fit in 80 cols):

---------------------------------------------------------------------------
asmlinkage void do_nmi(struct pt_regs * regs, long error_code)
{
#ifdef CONFIG_SMP_NMI_INVAL
smp_flush_tlb_rcv();
#else
#ifndef CONFIG_IGNORE_NMI
printk("Uhhuh. NMI received. Dazed and confused, but trying to continue\n");
printk("You probably have a hardware problem with your RAM chips or a\n");
printk("power saving mode enabled.\n");
#endif
#endif
