1/*
2 * structures and definitions for the int 15, ax=e820 memory map
3 * scheme.
4 *
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.
