    atomic.h: atomic_add_unless as inline. Remove system.h atomic.h circular 
dependency
    
    atomic_add_unless as inline. Remove system.h atomic.h circular dependency.
    I agree (with Andi Kleen) this typeof is not needed and more error
    prone. All the original atomic.h code that uses cmpxchg (which includes
    the atomic_add_unless) uses defines instead of inline functions,
    probably to circumvent a circular dependency between system.h and
    atomic.h on powerpc (which my patch addresses). Therefore, it makes
    sense to use inline functions that will provide type checking.
    
    atomic_add_unless as inline. Remove system.h atomic.h circular dependency.
    Digging into the FRV architecture shows me that it is also affected by
    such a circular dependency. Here is the diff applying this against the
    rest of my atomic.h patches.
    
    It applies over the atomic.h standardization patches.
