Make tiny RCU support leak callbacks for debug-object errors, courtesy of Zqiang. 5. Document reason for rcu_all_qs() call to preempt_disable(). 6. Update rcu_access_pointer() header for rcu_dereference_protected(). 7. Try trigger_single_cpu_backtrace(cpu) in dump_cpu_task(), courtesy of Zhen Lei. 8. Show the registers of 'current' in dump_cpu_task(), courtesy of Zhen Lei. 9. Avoid triggering strict-GP irq-work when RCU is idle, courtesy of Zqiang. 10. Exclude outgoing CPU when it is the last to leave.
