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