| 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. | |
