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