| 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". |

| ---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". |
