Hello!
This series contains miscellaneous fixes. The individual fixes are as
follows:
1. Add PROVE_RCU_DELAY Kconfig parameter to add delays as needed to
provoke difficult races.
2. Pull TINY_RCU dyntick-idle tracing into non-idle region.
3. Properly initialize ->boost_tasks on CPU offline.
4. Permit RCU_NONIDLE() to be used from interrupt context.
5. Improve boost selection when moving tasks to root rcu_node.
6. Make offline-CPU checking allow for indefinite delays.
7. Fix obsolete rcu_initiate_boost() header comment.
8. Apply for_each_rcu_flavor() to increment_cpu_stall_ticks().
9. Avoid segfault in rcu_print_detail_task_stall_rnp().
10. Protect rcu_node accesses during CPU stall warnings.
11. Avoid spurious RCU CPU stall warnings.
12. Remove redundant memory barrier from __call_rcu().
13. Move TINY_PREEMPT_RCU away from raw_local_irq_save().
14. RCU permitted to stop idle entry via softirq.
15. Replace kmemleak use of list_for_each_continue_rcu() with
list_for_each_entry_continue_rcu() (courtesy of Michael Wang).
Thanx, Paul
