| 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". |

| 22 | Say Y here if you want to check the overflows of kernel, IRQ |
| 23 | and exception stacks. This option will cause messages of the |
| 24 | stacks in detail when free stack space drops below a certain |
| 25 | limit. |
| 26 | If in doubt, say "N". |
