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"
