As requested, BFS has been made a simple config option to enable/disable in
kernel build. It is otherwise unchanged from .311.

A quick set of kernbench benchmarks on my quad core:

Note one person has had problems with preemptible tree based hierarchical rcu
and bfs 311 using high amounts of CPU, the cause of which remains unknown at
the moment. Probably safest to not use this combination for now.

Be nice,
enjoy!
