We intentionally discard the caller mandated alignment for debugging

Disagreed. The caller mandated alignment is not a hint. It is the
required minimum alignment for objects.

And it changes the basic way that slab debugging works.

Look at kmem_cache_create, we turn off debugging for both caller and
architecture mandated alignments already and the only reason we are
not doing it for Heiko is because the architecture recommended default
alignment is so large.
