SELinux: hold tasklist_lock and siglock while waking wait_chldexit
SELinux has long been calling wake_up_interruptible() on
current->parent->signal->wait_chldexit without holding any locks. It
appears that this operation should hold the tasklist_lock to dereference
current->parent and we should hold the siglock when waking up the
signal->wait_chldexit.
