Re: [PATCH] objtool/klp: Fix missed changes to same-named symbol references

At this patch's base commit (50d05c7c76c9), __checksum_update_object()
begins with:

        __checksum_update(sym, &offset, sizeof(offset));
        __checksum_update(sym, data, size);

__checksum_update_object_symbol() preserves the same offset handling,
including the unsigned long type and sizeof(offset). The difference is
how the referenced symbol's identity is encoded.

The same &offset/sizeof(offset) pattern is also used in
checksum_update_insn(). Any host-width dependence here therefore
predates this patch.

Thanks,
