Hello! This series contains miscellaneous fixes: 1. Don't invoke try_invoke_on_locked_down_task() with irqs disabled. 2. Move x86's rcu_cpu_starting() earlier. 3. Panic after fixed number of stalls. 4. Update list.h comment to explicitly note circular lists. 5. Implement rcu_segcblist_is_offloaded() config dependent. 6. Fix single-CPU check in rcu_blocking_is_gp(). 7. Clarify nocb kthreads naming in RCU_NOCB_CPU config. 8. Add a warning if CPU being onlined did not report QS already. 9. Make struct kernel_param_ops definitions const. 10. Fix ftrace recursion. 11. nocb: Avoid raising softirq for offloaded ready-to-execute CBs. 12. Prevent lockdep-RCU splats on lock acquisition/release. 13. Fix a typo in rcu_blocking_is_gp() header comment. 14. Do not report strict GPs for outgoing CPUs. 15. Defer kvfree_rcu() allocation to a clean context. 16. Take early exit on memory-allocation failure.
