	  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.



	  If this option is switched on, the /dev/mem file only allows

	  userspace access to memory mapped peripherals.
