This series contains miscellaneous fixes: 1. Make lockdep's print_lock() address visible. 2. Fix tick_broadcast_offline() lockdep complaint. 3. Restore barrier() to rcu_read_lock() and rcu_read_unlock(). 4. Add kernel parameter to dump trace after RCU CPU stall warning. 5. Add destroy_work_on_stack() to match INIT_WORK_ONSTACK(). 6. Avoid srcutorture security-based pointer obfuscation. 7. Change return type of rcu_spawn_one_boost_kthread(), courtesy of Byungchul Park. 8. Add rcutree.kthread_prio pointer to stallwarn.txt. 9. Prevent late-arriving interrupts from disrupting offline, courtesy of Peter Zijlstra. 10. Remove redundant "if" condition from rcu_gp_is_expedited(). 11. Use common outgoing-CPU-notification code for arm. 12. Fix spelling mistake "greate"->"great", courtesy of Mukesh Ojha.
