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".
