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
