* docs/multiboot.texi: Misc editorial changes:
	
	Avoid using `commercial' as a synonym for `non-free'
	(see http://www.gnu.org/philosophy/words-to-avoid.html#Commercial).
	
	Make a clear distinction between kernels and Operating Systems
	(Linux is a kernel, FreeBSD and NetBSD are Operating Systems, Mach
	is a microkernel, VSTa is something in-between).
	
	Use 64-bit types to describe 64-bit datum (instead of splitting in
	two 32-bit fields).  Little endianess assumption applies (as per
	Terminology section).
	
	Update status of GNU GRUB relative to version 2.
