This series contains miscellaneous fixes: 1. Merge identical definitions of the rcu_synchronize structure and the wakeme_after_rcu() functions. 2. Avoid needlessly writing to rnp->completed when a new grace period is started, courtesy of Lai Jiangshan. 3. Fix a couple of typos in rcu_all_qs() comment header. 4. Eliminate CONFIG_PROVE_RCU as a separately settable Kconfig parameter by driving its value off of CONFIG_PROVE_LOCKING. 5. Remove a #ifdef from tree.c by moving the rcu_init_levelspread() functions to tree_plugin.h. Only moves code. 6. Improve diagnostics for blocked critical sections in interrupt handlers. 7. Use IS_ENABLED() to simplify rcu_bootup_announce_oddness(). 8. Add rcu_bootup_announce_oddness() check for non-default CONFIG_RCU_FANOUT_LEAF values. 9. Reverse rcu_dereference_check() conditions to avoid invoking lockdep functions from NMI handlers. 10. Avoid script syntax error when insufficient CPUs. 11. Put rcu_sched_force_quiescent_state() back where it belongs. Only code movement. 12. Remove redundant check of cpu_online() by __call_rcu_core(), courtesy of Yao Dongdong. Thanx, Paul
