12	  Say Y here if you want to show the kernel pagetable layout in a
13	  debugfs file. This information is only useful for kernel developers
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

20# If you know what you are doing and are willing to live without stack

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
63	      8 - SIGSEGV faults

75	  Note that selecting this option will limit the kernel to a single
76	  UART definition, as specified below. Attempting to boot the kernel
77	  image on a different platform *will not work*, so this option should
78	  not be enabled for kernels that are intended to be portable.

1785	  This option influences the normal decompressor output for
1786	  multiplatform kernels.  Normally, multiplatform kernels disable
1787	  decompressor output because it is not possible to know where to
1788	  send the decompressor output.
1789
1790	  When this option is set, the selected DEBUG_LL output method
1791	  will be re-used for normal decompressor output on multiplatform
