-       ---help---
-         If this option is disabled, you allow userspace (root) access to all
-         of memory, including kernel and userspace memory. Accidental
-         access to this is obviously disastrous, but specific access can
-         be used by people debugging the kernel. Note that with PAT support
-         enabled, even in this case there are restrictions on /dev/mem
-         use due to the cache aliasing requirements.
-
-         If this option is switched on, the /dev/mem file only allows
-         userspace access to PCI space and the BIOS code and data regions.
-         This is sufficient for dosemu and X and all common users of
-         /dev/mem.

-         If in doubt, say Y.
