 * In a nutshell, arch/i386/boot/setup.S populates a scratch table
 * in the empty_zero_block that contains a list of usable address/size
 * duples.   In arch/i386/kernel/setup.c, this information is
 * transferred into the e820map, and in arch/i386/mm/init.c, that
 * new information is used to mark pages reserved or not.
