Hello!
This series contains miscellaneous fixes.
1. Drop RCU_USER_QS in favor of NO_HZ_FULL.
2. Deinline rcu_read_lock_sched_held() even in kernels built with
CONFIG_DEBUG_LOCK_ALLOC=y, courtesy of Denys Vlasenko.
3. Change srcu_readers_active()'s return type to bool, courtesy
of Nicholas Mc Guire.
4. Add RCU-sched flavors get-state/cond-sync functions, namely
get_state_synchronize_sched() and cond_synchronize_sched().
5. Hide RCU_NOCB_CPU behind RCU_EXPERT, arriving at fully
automated Kconfig setup for RCU.
6. Use WRITE_ONCE in RCU_INIT_POINTER, courtesy of Peter Zijlstra.
7. Fix obsolete priority-boosting comment.
8. Create a synchronize_rcu_mult() to allow overlapped synchronous
grace periods.
9. Use synchronize_rcu_mult() to make _cpu_down() wait for its
RCU and RCU-sched grace periods concurrently.
10. Make rcu_is_watching() really be notrace, courtesy of =
Alexei Starovoitov.
11. Rename rcu_lockdep_assert() to RCU_LOCKDEP_WARN().
12. Fix backwards RCU_LOCKDEP_WARN() in synchronize_rcu_tasks().
13. Clarify CONFIG_RCU_EQS_DEBUG help text.
14. Update RCU MAINTAINERS email address, courtesy of Lai Jiangshan.
15. Make checkpatch.pl warn on expedited RCU grace periods.
16. Don't disable CPU hotplug during OOM notifiers.
Thanx, Paul
