- * On IA-64, we don't want to hold the runqueue's lock during the low-level context-switch,

- *
- * Example:
- * CPU#0:
- * schedule()
- *    -> spin_lock_irq(&rq->lock)
- *    -> context_switch()
- *       -> wrap_mmu_context()
- *          -> read_lock(&tasklist_lock)

- * CPU#1:
- * sys_wait4() or release_task() or forget_original_parent()
- *    -> write_lock(&tasklist_lock)
- *    -> do_notify_parent()
- *       -> wake_up_parent()
- *          -> try_to_wake_up()
- *             -> spin_lock_irq(&parent_rq->lock)
- *
- * If the parent's rq happens to be on CPU#0, we'll wait for the rq->lock
- * of that CPU which will not be released, because there we wait for the
- * tasklist_lock to become available.
