| 11 | ---help--- |
| 12 | This option restricts access to /dev/mem. If this option is |
| 13 | disabled, you allow userspace access to all memory, including |
| 14 | kernel and userspace memory. Accidental memory access is likely |
| 15 | to be disastrous. |
| 16 | Memory access is required for experts who want to debug the kernel. |

| 18 | If you are unsure, say Y. |

| 25 | Say Y here if you want to show the kernel pagetable layout in a |
| 26 | debugfs file. This information is only useful for kernel developers |
| 27 | who are working in architecture specific areas of the kernel. |
| 28 | It is probably not a good idea to enable this feature in a production |
| 29 | kernel. |
| 30 | If in doubt, say "N" |
