2023-12-11kernel/amd64: Update arch(9)Ian Moffett
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. Signed-off-by: Ian Moffett <ian@osmora.org>
