Right, so the real issue is that what we have here is a lower
bound of the kmalloc alignment. In reality, the kmalloc return
values are cache-line aligned when debugging is off. So if you
can think of a way of getting a better bound at compile time,
I'm all ears.

Otherwise this discussion seems to be completely pointless.
