The rwsem-xadd count has been converted to an atomic variable and the
rwsem code now directly uses atomic_long_add() and
atomic_long_add_return(), so we can remove the arch implementations of
rwsem_atomic_add() and rwsem_atomic_update().

Nice. This, along with Michal's work getting rid of a lot of superfluous
implementations, have gotten rid of plenty of rwsem code in arch/*
Thanks,
