[PATCH tip/core/rcu 0/12]

["Paul E. McKenney" <paulmck@linux.ibm.com>]

Hello!

This series provides yet more cleanups and fixes for the RCU flavor
consolidation effort:

1.	Enable elimination of Tree-RCU softirq processing, courtesy of
	Sebastian Andrzej Siewior.  (More along the lines of real-time
	than consolidation, but placed here to avoid conflicts.)

2.	Check for wakeup-safe conditions in rcu_read_unlock_special().

3.	Only do rcu_read_unlock_special() wakeups if expedited.

4.	Allow rcu_read_unlock_special() to raise_softirq() if in_irq().

5.	Use irq_work to get scheduler's attention in clean context.

6.	Inline invoke_rcu_callbacks() into its sole remaining caller.

7.	Avoid self-IPI in sync_rcu_exp_select_node_cpus().

8.	Avoid self-IPI in sync_sched_exp_online_cleanup().

9.	Add assertion to check if in an interrupt, courtesy of Joel
	Fernandes.

10.	Add checks for dynticks counters in rcu_is_cpu_rrupt_from_idle(),
	courtesy of Joel Fernandes.

11.	Rename rcu_data's ->deferred_qs to ->exp_deferred_qs.

12.	Remove unused rdp local from synchronize_rcu_expedited(),
	courtesy of Jiang Biao.

							Thanx, Paul
