| 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". | |
