  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"

  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

  40           the performance is not affected. Currently, this feature

  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
  63              16 - SIGBUS faults

1675           This option influences the normal decompressor output for
1676           multiplatform kernels.  Normally, multiplatform kernels disable
1677           decompressor output because it is not possible to know where to
1678           send the decompressor output.
1679
1680           When this option is set, the selected DEBUG_LL output method
1681           will be re-used for normal decompressor output on multiplatform
1682           kernels.

1709           Enabling this option causes the kernel to write the current PID to

1718           This option helps catch unintended modifications to loadable
1719           kernel module's text and read-only data. It also prevents execution
1720           of module data. Such protection may interfere with run-time code
1721           patching and dynamic kernel tracing - and they might also protect
1722           against certain classes of kernel exploits.
1723           If in doubt, say "N".
