This series contains torture-test updates: 1. Move SRCU status printing to SRCU implementations. 2. Print SRCU lock/unlock totals because I am getting tired of doing the addition in my head. 3. Remove CONFIG_TASKS_RCU ifdef from rcuperf.c. 4. Select CONFIG_PROVE_LOCKING for Tiny SRCU scenario. 5. Add --kconfig argument to kvm.sh to allow test runs to override the test-scenario files. 6. Don't wait for kernel when all builds fail. 7. Enable SRCU readers from timer handler. 8. Place event-traced strings into trace buffer. 9. Use nr_cpus rather than maxcpus to limit test size. 10. Add task's CPU for rcutorture writer stalls. 11. Eliminate unused ts_rem local from rcu_trace_clock_local(). 12. Add last-CPU to GP-kthread starvation messages. 13. Invoke call_rcu() from timer handler.
