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. | |

24 | ---help--- | |
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" | |
