rcu: Convert local functions to static
The rcu_cpu_stall_timeout kernel parameter, the rcu_dynticks per-CPU variable, and the rcu_gp_fqs() function are used only locally. This commit therefore marks them as static. Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
