[PATCH tip/core/rcu 05/28] rcu: Move rcu_head definition to types.h

[Paul E. McKenney]

Take a first step towards untangling Linux kernel header files by
placing the struct rcu_head definition into include/linux/types.h.
Once this is in place, then header files that need only rcu_head
can include types.h rather than rcupdate.h.
