The mappings are not part of any other kernel PGD and are only available during EFI runtime calls. -The module mapping space size changes based on the CONFIG requirements for the -following fixmap section. - Note that if CONFIG_RANDOMIZE_MEMORY is enabled, the direct mapping of all physical memory, vmalloc/ioremap space and virtual memory map are randomized. Their order is preserved but their base will be offset early at boot time. |
