2025-09-15kernel/amd64: Add task state segment logicIan Moffett
This commit implements the task state segment and splits up processor initialization into two seperate stages. The cpu_conf() function is apart of the first stage and sets up things that should be going by the time the kernel is started / early init. The cpu_init() function runs later functions that initialize further platform specific subsystems. Signed-off-by: Ian Moffett <ian@osmora.org>
