smp_apic_timer_interrupt is also used in UP local APIC kernels. You're either running an SMP kernel on a UP box, or a local APIC enabled kernel.

You got a page fault in ack_APIC_irq(). This should never happen. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
