Peter Zijlstra e87fc0ec07 locking/atomic, arch/blackfin: Implement atomic_fetch_{add,sub,and,or,xor}() 
Implement FETCH-OP atomic primitives, these are very similar to the
existing OP-RETURN primitives we already have, except they return the
value of the atomic variable _before_ modification.

This is especially useful for irreversible operations -- such as
bitops (because it becomes impossible to reconstruct the state prior
to modification).
