| ---help--- | |
| This option restricts access to /dev/mem. If this option is | |
| disabled, you allow userspace access to all memory, including | |
| kernel and userspace memory. Accidental memory access is likely | |
| to be disastrous. | |
| Memory access is required for experts who want to debug the kernel. | |
| If you are unsure, say Y. | |

| ---help--- | |
| Say Y here if you want to show the kernel pagetable layout in a | |
| debugfs file. This information is only useful for kernel developers | |
| who are working in architecture specific areas of the kernel. | |
| It is probably not a good idea to enable this feature in a production | |
| kernel. | |
| If in doubt, say "N" | |
