Print number of online CPUs in RCU CPU stall-warning messages. 7. Fix preemption mode check on synchronize_rcu[_expedited](), courtesy of Frederic Weisbecker. 8. Drop needless initialization of sdp in srcu_gp_start(), courtesy of Lukas Bulwahn. 9. Check for successful spawn of ->boost_kthread_task, courtesy of Zqiang. 10. rcu_sync: Fix comment to properly reflect rcu_sync_exit() behavior, courtesy of David Vernet. 11.
