- depends on DEBUG_KERNEL
- help
- 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".

- depends on DEBUG_KERNEL
- ---help---
- 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".
