  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.

  18 # RMK wants arm kernels compiled with frame pointers or stack unwinding.
  19 # If you know what you are doing and are willing to live without stack
  20 # traces, you can get a slightly smaller kernel by setting this option to
  21 # n, but then RMK will have to kill you ;).

  27           If you say N here, the resulting kernel will be slightly smaller and
  28           faster. However, if neither FRAME_POINTER nor ARM_UNWIND are enabled,
  29           when a problem occurs with the kernel, the information that is

  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
