Active Reparenting In Young Brothers Wait Concept (YBWC) available slaves are booked by the split point master, then start to search below the assigned split point and, once finished, return in idle state waiting to be booked by another master. This patch introduces "Active Reparenting" so that when a slave finishes its job on the assigned split point, instead of passively waiting to be booked, searches a suitable active split point and reprents itselfs to that split point. Then immediately starts to search below the split point in exactly the same way of the others split point's slaves. This reduces to zero the time waiting in idle loop and should increase scalability especially whit many (8 or more) cores. No functional change. Signed-off-by: Marco Costalba <mcostalba@gmail.com>
