  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".
