Subject[RFC][PATCH 5/7] locking,ia64: Remove ia64 rwsem add and rwsem update
Date
The rwsem 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 ia64 implementation of rwsem_atomic_add() and
rwsem_atomic_update().
