Hello! This series introduces a new torture test for smp_call_function() and friends: 1. Add smp_call_function() torture test. 2. Declare parse-console.sh independence from rcutorture. 3. Add scftorture to the rcutorture scripting. 4. Implement weighted primitive selection. 5. tick-sched: Clarify "NOHZ: local_softirq_pending" warning. 6. Summarize per-thread statistics. 7. Add smp_call_function_single() memory-ordering checks. 8. Add smp_call_function_many() memory-ordering checks. 9. Add smp_call_function() memory-ordering checks. 10. Consolidate scftorture_invoke_one() check and kfree(). 11. Consolidate scftorture_invoke_one() scf_check initialization. 12. Flag errors in torture-compatible manner. 13. Prevent compiler from reducing race probabilities. 14. Make symbol 'scf_torture_rand' static. 15. Check unexpected "switch" statement value. 16. Block scftorture_invoker() kthreads for offline CPUs. 17. Adapt memory-ordering test to UP operation. 18. Add cond_resched() to test loop. 19. Change rcuperf to rcuscale.
