Subject: [PATCH tip/core/rcu 06/47] rcu: Move RCU_TRACE to lib/Kconfig.debug

From: "Paul E. McKenney" <paul.mckenney@...aro.org>

The RCU_TRACE kernel parameter has always been intended for debugging,
not for production use.  Formalize this by moving RCU_TRACE from
init/Kconfig to lib/Kconfig.debug.
