Subject: [PATCH tip/core/rcu 0/6] Miscellaneous fixes for v4.16

Hello!

This series provides miscellaneous fixes:

1.	Prohibit call_srcu() use under raw spinlocks.  This feature is
	not currently used and causes trouble for the -rt guys.

2.	Change printk() %p to %pK in SRCU.

3.	Change printk() %p to %pK in RCU.

4.	Hide trace event rcu_nocb_wake when not used, courtesy of Steven
	Rostedt.

5.	Add comment giving debug strategy for double call_rcu().

6.	Remove have_rcu_nocb_mask from tree_plugin.h, courtesy of
	Rakib Mullick.

							Thanx, Paul
