This series contains miscellaneous fixes for 4.6: 1. rcu: Assign false instead of 0 for ->core_needs_qs 2. Update rcu_report_qs_rsp() comment for RCU's grace-period kthreads. 3. Stop treating in-kernel CPU-bound workloads as errors, and stop IPIing such CPUs unless it is necessary. (If the loop contains cond_resched_rcu_qs(), then it is not necessary!) 4. Set rdp->gpwrap when CPU is idle instead of doing it backwards. 5. Correct no-expedite console messages. 6. Remove useless rcu_data_p when !PREEMPT_RCU, courtesy of Chen Gang. 7-9. Allow fields to be marked private to allow sparse to complain about unauthorized access for rcu_node:: lock and irq_common_data::state_use_accessors, courtesy of Boqun Feng. 10. Make rcu/tiny_plugin.h explicitly non-modular, courtesy of Paul Gortmaker. 11. Document unique-name limitation for DEFINE_STATIC_SRCU(), which results from the same per-CPU variable limitation. 12. Catch up rcu_report_qs_rdp() comment with reality. 13. Remove rcu_user_hooks_switch, courtesy of Yang Shi.
