Hello!
This series provides miscellaneous fixes:
1. Apply ACCESS_ONCE() to unprotected ->gp_flags accesses.
2. Fix typo in comment, courtesy of Liu Ping Fan.
3. Make RCU CPU stall warnings print grace-period numbers in
signed format to improve readability of stall-warning output.
4. Make cpu_needs_another_gp() take future grace-period needs
into account.
5. Remove unused ->preemptible field from the rcu_data structure,
courtesty of Iulia Manda.
6. Apply ACCESS_ONCE() to unprotected ->jiffies_stall accesses,
courtesty of Iulia Manda.
7. Make callers responsible for grace-period kthread wakeup in
order to avoid potential silent grace-period stalls.
8. Remove "extern" from RCU function declarations, courtesy of
Iulia Manda.
9. Apply ACCESS_ONCE() to additional ->jiffies_stall accesses,
courtesy of Himangi Saraogi.
10. Add event tracing to dyntick_save_progress_counter(), courtesy
of Andreea-Cristina Bernat.
11. Make rcu_init_one() use nr_cpu_ids instead of NR_CPUS for
data-structure setup limit check, courtesy of Himangi Saraogi.
12. Remove redundant kfree_call_rcu() definition by using the
rcu_state pointer, courtesy of Andreea-Cristina Bernat.
13. Merge rcu_sched_force_quiescent_state() definition with
rcu_force_quiescent_state() by using the rcu_state pointer,
courtesy of Andreea-Cristina Bernat.
14. Document RCU_INIT_POINTER()'s lack of ordering guarantees.
15. Automatically bind RCU's grace-period kthreads to timekeeping
CPU for NO_HZ_FULL builds.
16. Make large and small sysidle systems use equivalent state machine.
17. Remove duplicate resched_cpu() declaration, courtesy of
Pranith Kumar.
18. Replace deprecated __this_cpu_ptr() uses with raw_cpu_ptr(),
courtesy of Christoph Lameter.
19. Make softirq processing provide a quiescent state only once
per full pass over all softirqs rather than once per action,
courtesy of Eric Dumazet.
Thanx, Paul
