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...

I'll do this for the whole patchset. Stay tuned for the resubmit.
