Hello!

This series provides miscellaneous fixes:

1.	Fix to include first blocked task in stall warning, courtesy of
	Yanfei Xu.

2.	Fix stall-warning deadlock due to non-release of rcu_node ->lock,
	courtesy of Yanfei Xu.

3.	Remove special bit at the bottom of the ->dynticks counter,
	courtesy of "Joel Fernandes (Google)".

4.	Weaken ->dynticks accesses and updates.

5.	Mark accesses to ->rcu_read_lock_nesting.

6.	Unify documentation about missing list_empty_rcu(), courtesy of
	Julian Wiedmann.

7.	Handle VM stoppage in stall detection, courtesy of Sergey
	Senozhatsky.

8.	Do not disable GP stall detection in rcu_cpu_stall_reset(),
	courtesy of Sergey Senozhatsky.

9.	Start timing stall repetitions after warning complete.

10.	Mark read-side data races.

11.	Mark lockless ->qsmask read in rcu_check_boost_fail().

12.	Make rcu_gp_init() and rcu_gp_fqs_loop noinline to conserve stack.

13.	Remove trailing spaces and tabs, courtesy of Zhen Lei.

14.	Mark accesses in tree_stall.h.

15.	Remove useless "ret" update in rcu_gp_fqs_loop(), courtesy of
	Liu Song.

16.	Use per_cpu_ptr to get the pointer of per_cpu variable, courtesy
	of Liu Song.

17.	Explain why rcu_all_qs() is a stub in preemptible TREE RCU,
	courtesy of Frederic Weisbecker.

18.	Print human-readable message for schedule() in RCU reader.

						Thanx, Paul
