Alexey has pointed out a bug in my changes.
@@ -1088,6 +1086,9 @@ void smp_percpu_timer_interrupt(struct p : /* no outputs */ : "r" (pstate)); } while (time_after_eq(tick, compare)); + + local_irq_enable(); + irq_exit(); } static void __init smp_setup_percpu_timer(void)
Of course this is bogus.
The IRQ enable needs to occur in the irq_exit() branch right before do_softirq() is invoked. - 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/
