+       help
+         Mark the kernel read-only data as write-protected in the pagetables,
+         in order to catch accidental (and incorrect) writes to such const
+         data. This option may have a slight performance impact because a
+         portion of the kernel code won't be covered by a TLB anymore.
+         If in doubt, say "N".
