 | 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. | 
 | 17 |  | 
 | 18 | 	  If you are unsure, say Y. |

 | 24 | 	  Enabling this option turns a certain set of sanity checks for user | 
 | 25 | 	  copy operations into compile time warnings. | 
 | 26 |  | 
 | 27 | 	  The copy_from_user() etc checks are there to help test if there | 
 | 28 | 	  are sufficient security checks on the length argument of | 
 | 29 | 	  the copy operation, by having gcc prove that the argument is | 
 | 30 | 	  within bounds. | 
 | 31 |  | 
 | 32 | 	  If unsure, or if you run an older (pre 4.4) gcc, say N. |
