Lai Jiangshan 0cff810f54 rcu: Fix local_irq_disable() CONFIG_PROVE_RCU=y false positives ... It is documented that local_irq_disable() also delimits RCU_SCHED read-site critical sections. See the document of synchronize_sched() or Documentation/RCU/whatisRCU.txt. So we have to test irqs_disabled() in rcu_read_lock_sched_held(). Otherwise rcu-lockdep brings incorrect complaint.
