    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
    }
