Hey all,

From sys/arch/alpha/alpha/interrupt.c:

/* --8<-- */
	case ALPHA_INTR_CLOCK:	/* clock interrupt */
		/*
		 * We don't increment the interrupt depth for the
		 * clock interrupt, since it is *sampled* from
		 * the clock interrupt, so if we did, all system
		 * time would be counted as interrupt time.
		 */
		sc->sc_evcnt_clock.ev_count++;
		uvmexp.intrs++;
/* --8<-- */

Doesn't uvmexp.intrs++; need to be made atomic on MULTIPROCESSOR?
