    The nmi_timer_int oprofile driver was enabling itself unconditionally if an
    SMP kernel was being used on a UP system without an IOAPIC.
    
    Tested on a P5 using NMI timer int driver and UP system using timer int
    driver both running an SMP kernel.

    	* arch/i386/kernel/nmi.c: export nmi_active
    	* arch/i386/oprofile/nmi_timer_int.c: use it to check if owe can use
    	  an nmi interrupt
