13 Say Y here if you want to show the kernel pagetable layout in a
14 debugfs file. This information is only useful for kernel developers
15 who are working in architecture specific areas of the kernel.
16 It is probably not a good idea to enable this feature in a production

24 ---help---
25 Generate a warning if any W+X mappings are found at boot.
27 This is useful for discovering cases where the kernel is leaving
28 W+X mappings after applying NX, as such mappings are a security risk.
30 Look for a message in dmesg output like this:
32 arm/mm: Checked W+X mappings: passed, no W+X pages found.
34 or like this, if the check failed:
36 arm/mm: Checked W+X mappings: FAILED, <N> W+X pages found.
38 Note that even if the check fails, your kernel is possibly
39 still fine, as W+X mappings are not a security hole in
40 themselves, what they do is that they make the exploitation
41 of other unfixed kernel bugs easier.
43 There is no runtime or memory usage effect of this option
44 once the kernel has booted up - it's a one time check.
46 If in doubt, say "Y".

88 When a user program crashes due to an exception, the kernel can

94 line to enable this feature. N consists of the sum of:
