  66	  sometimes helpful for debugging but serves no purpose on a
  67	  production system. Most people should say N here.
  68
  69	  In addition, you need to pass user_debug=N on the kernel command
  70	  line to enable this feature.  N consists of the sum of:
  71
  72	      1 - undefined instruction events
  73	      2 - system calls
