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". | |
