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

29 when a problem occurs with the kernel, the information that is

37 This option enables stack unwinding support in the kernel
38 using the information automatically generated by the
39 compiler. The resulting kernel image is slightly bigger but
40 the performance is not affected. Currently, this feature
41 only works with EABI compilers. If unsure say Y.

51 When a user program crashes due to an exception, the kernel can
52 print a brief message explaining what the problem was. This is
53 sometimes helpful for debugging but serves no purpose on a
54 production system. Most people should say N here.
55
56 In addition, you need to pass user_debug=N on the kernel command
57 line to enable this feature. N consists of the sum of:
58
59 1 - undefined instruction events
60 2 - system calls
61 4 - invalid data aborts
62 8 - SIGSEGV faults
63 16 - SIGBUS faults

76 image on a different platform *will not work*, so this option should

1702 This option influences the normal decompressor output for
1703 multiplatform kernels. Normally, multiplatform kernels disable
1704 decompressor output because it is not possible to know where to
1705 send the decompressor output.
1706
1707 When this option is set, the selected DEBUG_LL output method
1708 will be re-used for normal decompressor output on multiplatform
1709 kernels.

1745 This option helps catch unintended modifications to loadable
1746 kernel module's text and read-only data. It also prevents execution
1747 of module data. Such protection may interfere with run-time code
1748 patching and dynamic kernel tracing - and they might also protect
1749 against certain classes of kernel exploits.
1750 If in doubt, say "N".
