rcu: Substitute lookup for bit-twiddling in sync_rcu_exp_select_node_cpus() The code in sync_rcu_exp_select_node_cpus() calculates the current CPU's mask within its rcu_node structure's bitmasks, but this has already been computed in the ->grpmask field of that CPU's rcu_data structure. This commit therefore just uses this ->grpmask field. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
