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.
16 If in doubt, say "N"

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

75 cost due to increased TLB pressure.
