McKenney <paulmck@xxxxxxxxxxxxxxxxxx> CommitDate: Wed, 27 May 2015 12:59:06 -0700 rcu: Remove prompt for RCU implementation The RCU implementation is chosen based on PREEMPT and SMP config options and is not really a user-selectable choice. This commit removes the menu entry, given that there is not much point in calling something a choice when there is in fact no choice.. The TINY_RCU, TREE_RCU, and PREEMPT_RCU Kconfig options continue to be selected based solely on the values of the PREEMPT and SMP options.
