atomic_testandset_int seems unimplemented

My reading of atomic(9) implies that the atomic_testandset_* family of 
functions should be present
on the arm architecture, however I don't see any evidence of it in any 
of the expected locations,

Is there some impediment within the architecture which doesn't make that 
semantic possible or is
it just that there is no in-tree consumer yet?

Any thoughts on this matter would be appreciated, or better yet a 
possible implementation - sadly for
me assembly is not my strength.
