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