	# The multiboot standard does not define the value of the stack pointer register called the following:
	# %rsp in 64bit mode, %esp in 32bit mode and %sp in 16bit mode.
	# It is up to the kernel to provide a stack, so basic languages like C and C++ can run.
	# Our stack will have an ELF symbol at the bottom, and then 16 KiB of free space. There is a symbol at the top
