/**
* @file
*
* START
* =====
*
* Defines the following sections/functions, some are linked at
* specific addresses in the final ELF kernel binary.
* This is specified in the _linker.ld_ file.
*
* * 0x007000 .smp - entry point for application processors (16bit code) _start_smp() calls finally smp_main()
* * 0x100000 .multiboot - the multiboot header
*
* __TODO: Does this not kill the memory in-between?__
*
* * .text
* * .bootstrap_stack
* * _start() - main entry point for booting cpu, calls kernel_main().
*
* The addresses for .smp and .multiboot are based on the assumption:
* * 0x00000500 - 0x00007BFF : guaranteed free to use
* * 0x00100000 - 0x00EFFFFF : free for use (if it exists)
*
