15 ---help---
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

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

69 This option enables stack unwinding support in the kernel
70 using the information automatically generated by the
71 compiler. The resulting kernel image is slightly bigger but
72 the performance is not affected. Currently, this feature
73 only works with EABI compilers. If unsure say Y.

82 help
83 When a user program crashes due to an exception, the kernel can
84 print a brief message explaining what the problem was. This is
85 sometimes helpful for debugging but serves no purpose on a
86 production system. Most people should say N here.
88 In addition, you need to pass user_debug=N on the kernel command
89 line to enable this feature. N consists of the sum of:
91 1 - undefined instruction events
92 2 - system calls
93 4 - invalid data aborts
94 8 - SIGSEGV faults
95 16 - SIGBUS faults

106 Note that selecting this option will limit the kernel to a single
107 UART definition, as specified below. Attempting to boot the kernel
