Grep'ing the old git logs for the arm64 development, it looks like it
was introduced as part of the first proposal for the booting protocol
where all the CPUs got into the kernel at the same time (secondaries at
offset 0x80). IIRC you nak'ed this during the private review but we
forgot about this section.
