Sadly you over estimated us here :-) We do 16K *and* irq stacks on 64-bit ... Remember our ABI with it's 112 bytes minimum per frame ? It's been a while since I've last audited our actual usage mind you, we *might* be able to reduce it but at this stage, since our typical configs use a 64K base page size, it's not a big deal (ie, it's not an order-N allocation).
