    Subject[PATCH tip/core/rcu 10/28] rcu: Fix RCU's NMI documentation
    Date
    It has long been the case that the architecture must call nmi_enter()
    and nmi_exit() rather than irq_enter() and irq_exit() in order to
    permit RCU read-side critical sections in NMIs. Catch the documentation
    up with reality.
