    Subject[PATCH tip/core/rcu 14/17] rcu: Fix rcu_is_cpu_idle() #ifdef in TINY_RCU
    Date
    From: "Paul E. McKenney" <paul.mckenney@linaro.org>

    The rcu_is_cpu_idle() function is used if CONFIG_DEBUG_LOCK_ALLOC,
    but TINY_RCU defines it only when CONFIG_PROVE_RCU. This causes
    build failures when CONFIG_DEBUG_LOCK_ALLOC=y but CONFIG_PROVE_RCU=n.
    This commit therefore adjusts the #ifdefs for rcu_is_cpu_idle() so
    that it is defined when CONFIG_DEBUG_LOCK_ALLOC=y.
