Hello!

This series provides a couple of updates to the RCU Tasks flavors.

1.	rcu-tasks: Use order_base_2() instead of ilog2().
	This spreads CPUs over queues more evenly.

2.	rcu-tasks: Set ->percpu_enqueue_shift to zero upon contention.
	The current mainline series reduces contention by at most a
	factor of two.	This patch gains at least another factor of
	eight during times of high update-side traffic.

						Thanx, Paul
