rcu: Move torture-related functions out of rcutiny.h and rcutree.h
The various functions similar to rcu_batches_started(), the function show_rcu_gp_kthreads(), the various functions similar to rcu_force_quiescent_state(), and the variables rcutorture_testseq and rcutorture_vernum are used only within RCU. There is therefore no point in exporting them to the kernel at large from include/linux/rcutiny.h and include/linux/rcutree.h. This commit therefore moves all of these to kernel/rcu/rcu.h. Reported-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
