  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.

  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

1165                   Semihosting enables code running on an ARM target to use
1166                   the I/O facilities on a host debugger/emulator through a
1167                   simple SVC call. The host debugger or emulator must have
1168                   semihosting enabled for the special svc call to be trapped
1169                   otherwise the kernel will crash.

1633           of module data. Such protection may interfere with run-time code

1635           against certain classes of kernel exploits.
