bool "Write protect kernel read-only data structures"
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".

default y
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".
