+	  NOTE: This option is security sensitive, because it allows arbitrary
+	  kernel memory to be written to by root (uid=0) users, allowing them
+	  to bypass certain security measures (e.g. if root is not allowed to
+	  load additional kernel modules after boot, this feature may be used
+	  to override that restriction).
