rcu: Move rcu_{expedited,normal} definitions into rcupdate.h

This commit moves the rcu_{expedited,normal} definitions from kernel/rcu/update.c to include/linux/rcupdate.h to make sure they are in sync, and also to avoid the following warning from sparse: kernel/ksysfs.c:150:5: warning: symbol 'rcu_expedited' was not declared. Should it be static? kernel/ksysfs.c:167:5: warning: symbol 'rcu_normal' was not declared. Should it be static? Signed-off-by: Ben Dooks <[email protected]> Signed-off-by: Paul E. McKenney <[email protected]>
