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

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

70 This option enables stack unwinding support in the kernel

73 the performance is not affected. Currently, this feature

84 When a user program crashes due to an exception, the kernel can
85 print a brief message explaining what the problem was. This is
86 sometimes helpful for debugging but serves no purpose on a
87 production system. Most people should say N here.
89 In addition, you need to pass user_debug=N on the kernel command
90 line to enable this feature. N consists of the sum of:
92 1 - undefined instruction events
93 2 - system calls
94 4 - invalid data aborts
95 8 - SIGSEGV faults
96 16 - SIGBUS faults
