prompt "Filter access to /dev/mem" |

---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" |
