Personally I don't see how these define/undef are better then inline functions...
Again I suppose they might be re-used in future some other ARM specific low-level primitvies.
My preference would be to keep them as inline function - much cleaner code.
But as I don't develop for/use, I wouldn't insist and let you and arm guys to decide.
