Cover letter [PATCH v3 tip/core/rcu 0/18] Miscellaneous fixes for 4.11
Hello!
This series provides v3 of miscellaneous fixes:
1. Make RCU_EXPEDITE_BOOT be the default in order to speed up
boot, courtesy of Sebastian Andrzej Siewior.
2. Make RCU suspicious-access lockdep splats use pr_err().
3. Disable sys_membarrier when nohz_full is enabled, courtesy
of Mathieu Desnoyers.
4. Only dump stalled-tasks stacks if there was a real stall, courtesy
of Byungchul Park.
5. Remove unneeded rcu_process_callbacks() declarations.
6. Remove unused but set "mask" variable, courtesy of Tobias Klauser.
7. Add long-term CPU kicking.
8. Remove short-term CPU kicking.
9. Once again use NMI-based stack traces in stall warnings.
10. Re-enable TASKS_RCU for User Mode Linux.
11. Don't wake rcuc/X kthreads on NOCB CPUs.
12. Add comment headers to expedited-grace-period counter functions.
13. Make rcu_cpu_starting() use its "cpu" argument.
14. Enable RCU tracepoints by default to aid in debugging, courtesy
of Matt Fleming.
15. Fix comment in rcu_organize_nocb_kthreads(), which no longer
spawns kthreads.
16. Clarify comments about when llist locking is needed, courtesy
of Joel Fernandes.
17. Eliminate unused expedited_normal counter.
18. Add lockdep checks to synchronous expedited primitives.
Changes since v2:
o Fixed lockdep message as noted by Josh Triplett.
Changes since v1:
o Reverse the order of patches 7 and 8.
o Defer the patch adding tests for trivial grace periods.
o Defer the patch making cond_resched() provide RCU quiescent
states.
o Apply other feedback from Josh Triplett, Peter Zijlstra, and
Michal Hocko.
Thanx, Paul
