rcu: Replace the rcu_barrier enum with pointer to call_rcu*() function
The rcu_barrier enum causes several problems: (1) you have to define the enum somewhere, and there is no convenient place, (2) the difference between TREE_RCU and TREE_PREEMPT_RCU causes problems when you need to map from rcu_barrier enum to struct rcu_state, (3) the switch statement are large, and (4) TINY_RCU really needs a different rcu_barrier() than do the treercu implementations. So replace it with a functionally equivalent but cleaner function pointer abstraction. Signed-off-by: Paul E.
