rcu: Remove unneeded __rcu_process_callbacks() argument
With the advent of __this_cpu_ptr(), it is no longer necessary to pass both the rcu_state and rcu_data structures into __rcu_process_callbacks(). This commit therefore computes the rcu_data pointer from the rcu_state pointer within __rcu_process_callbacks() so that callers can pass in only the pointer to the rcu_state structure. This paves the way for linking the rcu_state structures together and iterating over them. Signed-off-by: Paul E.
