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".

Say Y here if you want to check the overflows of kernel, IRQ
|
|
and exception stacks. This option will cause messages of the
|
|
stacks in detail when free stack space drops below a certain
|
|
limit.
|
|
If in doubt, say "N".
