A return value >= 0 means call do_notify_parent with that signal
number. Negative return value can be DEATH_REAP to self-reap right
now, or DEATH_DELAYED_GROUP_LEADER to a zombie without notifying our
parent. Note that a return value of 0 means a do_notify_parent call
that sends no signal, but still wakes up a parent blocked in wait*().
Called with write_lock_irq(tasklist_lock) held.
