Hello!

This series adds RCU Tasks diagnostics and documentation:

1.	Check processor-ID assumptions.

2.	Update rtp->tasks_gp_seq comment.

3.	Provide rcu_barrier_cb_is_done() to check rcu_barrier() CBs.

4.	Mark callbacks not currently participating in barrier operation.

5.	Add detailed grace-period and barrier diagnostics.

6.	Add rcu_barrier_tasks*() start time to diagnostics.

						Thanx, Paul
