rcu: Disable preemption in rcu_blocking_is_gp() It is time to optimize CONFIG_TREE_PREEMPT_RCU's synchronize_rcu() for uniprocessor optimization, which means that rcu_blocking_is_gp() can no longer rely on RCU read-side critical sections having disabled preemption. This commit therefore disables preemption across rcu_blocking_is_gp()'s scan of the cpu_online_mask. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
