This commit cleans up arch(9) as a few things were
noticed. First, it would make sense to identify cores (described by
the cpu_info structure) in every arch ported, thus
the lapic_id has been changed to id so it can be shared. Some
annotations have also been added for the sake of clarity. The manpage
for arch(9) has also been cleaned up.

This commit moves the interrupts_init() and gdt_load()
calls to the top so interrupts are set up first in case
something goes wrong so we can get information from
exception handlers.
