Subject[PATCH tip/core/rcu 0/16] Miscellaneous fixes for v5.11
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.

Thanx, Paul
