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

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

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

1767 This option influences the normal decompressor output for
1768 multiplatform kernels. Normally, multiplatform kernels disable
1769 decompressor output because it is not possible to know where to
1770 send the decompressor output.
1771
1772 When this option is set, the selected DEBUG_LL output method
1773 will be re-used for normal decompressor output on multiplatform
1774 kernels.
