+         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.

+         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.
