This patch series contains a cleanup and a fix:

o Code cleanup from Lai Jiangshan that makes the calls to
rcu_irq_enter() and rcu_irq_exit() more obviously correct.
The previous code worked because rcu_irq_exit() is always
an empty function if !NO_HZ.

o Fix a low-probability race in the TREE_RCU infrastructure
that can be triggered by extremely long grace periods.

Thanx, Paul
