Oh, I didn't notice you changed the semantics. x86_32 %gs points to `segment_data`, while x86_64 points to `cpu_infos`. Can you leave the semantics how they were so it's not confusing? I think if you leave %gs pointing to `segment_data` you can leave this function unchanged since the `mov %gs:0` should correctly work.
