From: Ming Lei <tom.leiming@xxxxxxxxx>

This series does the BFS optimizations:

	.reintroduce DaveM's generation id to bfs to make it faster
	.make bfs preallocated "stack" as per cpu variable
	.add likely/unlikely annotations to BFS core routine

and the patches are based on Peter's patches against tip:core/locking:

	http://marc.info/?l=linux-kernel&m=124793787804558&w=2
	http://marc.info/?l=linux-kernel&m=124793787804556&w=2

Also, the patches have passed lockdep's selftest.
