Subject: [PATCH rcu 0/5] Miscellaneous fixes

Hello!

This series contains miscellaneous fixes:

1.	Split rcu_report_exp_cpu_mult() mask parameter and use for
	tracing.

2.	Remove READ_ONCE() for rdp->gpwrap access in __note_gp_changes(),
	courtesy of Zilin Guan.

3.	Fix get_state_synchronize_rcu_full() GP-start detection.

4.	Move RCU Tasks self-tests to core_initcall().

5.	Print segment lengths in show_rcu_nocb_gp_state().

Changes since v1:

o	Fix "the the" in commit log.

o	Add Reviewed-by and Tested-by tags.

						Thanx, Paul
