From 8008e129dc90ff4f7a56cb033d6bd042afe3ed52 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 8 Jun 2011 16:31:33 -0700 Subject: [PATCH] rcu: Drive configuration directly from SMP and PREEMPT This commit eliminates the possibility of running TREE_PREEMPT_RCU when SMP=n and of running TINY_RCU when PREEMPT=y. People who really want these combinations can hand-edit init/Kconfig, but eliminating them as choices for production systems reduces the amount of testing required. It will also allow cutting out a few #ifdefs. Note that running TREE_RCU and TINY_RCU on single-CPU systems using SMP-built kernels is still supported. Signed-off-by: Paul E.
