Merge branch 'rcu/urgent' of git://git./linux/kernel/git/paulmck/linux-rcu

Pull RCU fix from Paul McKenney:
 "This contains a single commit that fixes a bug that was introduced in
  the last merge window. This bug causes a compiler warning complaining
  about show_rcu_tasks_classic_gp_kthread() being an unused static
  function in !SMP kernels.

  The fix is straightforward, just adding an 'inline' to make this a
  static inline function, thus avoiding the warning.

  This bug was reported by Laurent Pinchart, who would like it fixed
  sooner rather than later"
