| ---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" |
