Introduce for_each_process_rculock(), for_each_thread_rculock() and
for_each_process_thread_rculock() macros that acquire the RCU read
lock before the iteration starts and release it when the loop is left,
so that the RCU read-side critical section is scoped to the loop body
instead of an externally managed rcu_read_lock()/rcu_read_unlock()
pair.

Looks good to me.
