There's no such thing as x32 kernels. It's an ABI atop amd64 kernels; the
kernel is always 64-bit -- short pointers apply only to userspace and
syscalls.

It could be interesting to block regular amd64 syscalls and leave x32 only
-- for "security through rarity", but the kernel itself would still look the
same.
