  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"
