+  * @file
+  * 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)
+  * * 0x100000  .multiboot - the multiboot header
+  *
+  * * .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)
