srcu: Introduce srcu_read_{un,}lock_notrace()
Joel Fernandes is using SRCU to protect from-idle tracepoints, which
requires notrace variants of srcu_read_lock() and srcu_read_unlock()
in order to avoid problems with tracepoints in lockdep. This commit
therefore adds srcu_read_lock_notrace() and srcu_read_unlock_notrace().
