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

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