Is there any other way to get an indication then?  This is also in ia64 code
though not with the formality of a callback -- it's a static function pointer:

arch/ia64/kernel/process.c:
	void (*ia64_mark_idle)(int);

arch/ia64/sn/kernel/setup.c:
	ia64_mark_idle = &snidle;

arch/ia64/sn/kernel/idle.c
	void snidle(int state)
	{
	        if (state) {
	                if (pda->idle_flag == 0) {
	                        /*
	                         * Turn the activity LED off.
        	                 */
        	                set_led_bits(0, LED_CPU_ACTIVITY);
        	        }

	       	        pda->idle_flag = 1;
	        } else {
	                /*
	                 * Turn the activity LED on.
	                 */
	                set_led_bits(LED_CPU_ACTIVITY, LED_CPU_ACTIVITY);

	                pda->idle_flag = 0;
	        }
	}

As I mentioned, I would be happy to use an alternative but I haven't yet found one.
Should I put the above into x86_64?

Thanks,
Mike
