Could you just make the "atomic_read()" and "atomic_set()" functions be 
inline functions instead?

That way you get nice compiler warnings when you pass the wrong kind of 
object around.  So

	static void atomic_set(atomic_t *p, int value)
	{
		*(volatile int *)&p->value = value;
	}

	static int atomic_read(atomic_t *p)
	{
		return *(volatile int *)&p->value;
	}

etc...
