I can handle this in the clockevents code, but I think acpi > is the correct place. So the CONFIG_GENERIC_CLOCKEVENTS=y case is broken, but the CONFIG_GENERIC_CLOCKEVENTS=n below is okay? Not immediately clear why both cases can't fail. Maybe Venki can explain. -Len static void acpi_propagate_timer_broadcast(struct acpi_processor *pr) { #ifdef CONFIG_GENERIC_CLOCKEVENTS unsigned long reason; reason = pr->power.timer_broadcast_on_state < INT_MAX ? CLOCK_EVT_NOTIFY_BROADCAST_ON : CLOCK_EVT_NOTIFY_BROADCAST_OFF; clockevents_notify(reason, &pr->id); #else cpumask_t mask = cpumask_of_cpu(pr->id); if (pr->power.timer_broadcast_on_state < INT_MAX) on_each_cpu(switch_APIC_timer_to_ipi, &mask, 1, 1); else on_each_cpu(switch_ipi_to_APIC_timer, &mask, 1, 1); #endif } - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
