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
17 kernel.

25 Generate a warning if any W+X mappings are found at boot.
26
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.
29
30 Look for a message in dmesg output like this:
31
32 arm/mm: Checked W+X mappings: passed, no W+X pages found.
33
34 or like this, if the check failed:
35
36 arm/mm: Checked W+X mappings: FAILED, <N> W+X pages found.
37
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.
42
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.
45
46 If in doubt, say "Y".

87 help
88 When a user program crashes due to an exception, the kernel can
89 print a brief message explaining what the problem was. This is
90 sometimes helpful for debugging but serves no purpose on a
91 production system. Most people should say N here.
92
93 In addition, you need to pass user_debug=N on the kernel command
94 line to enable this feature. N consists of the sum of:
95
96 1 - undefined instruction events
97 2 - system calls
98 4 - invalid data aborts
99 8 - SIGSEGV faults

1841 This option influences the normal decompressor output for
1842 multiplatform kernels. Normally, multiplatform kernels disable
1843 decompressor output because it is not possible to know where to
1844 send the decompressor output.

1846 When this option is set, the selected DEBUG_LL output method
1847 will be re-used for normal decompressor output on multiplatform
