In the kernel should work as it's prepared for those kinds of optimisations,
but kernel modules should not, as they rely on the indirection persisting and
being rewritten on load. Marking the special vnet and dpcpu symbols as weak
might be sufficient to stop the relaxations, but I wouldn't like to say for
sure, kernel modules get build with weird symbol interposition semantics that
have always been asking for trouble.
