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