I thought about that. They are not really actively used by the linker, but they might be used by kernel descriptor.

I also considered deferring KD emission to the linker, but apparently KD has more fields that the linker can't really fill in, so we have to emit it here and then patch things up.

However, we might be able to emit some placeholder here for those fields that will be patched by the linker at link time. WDYT?
