  12           Say Y here if you want to show the kernel pagetable layout in a

  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.

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

  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
