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.
