   9           Kprobes allows you to trap at almost any kernel address and
  10           execute a callback function.  register_kprobe() establishes
  11           a probepoint and specifies the callback.  Kprobes is useful
  12           for kernel debugging, non-intrusive instrumentation and testing.
  13           If in doubt, say "N".

  41           are compiling for an Itanium A step processor

  48           The Virtual Hash Page Table (VHPT) enhances virtual address
  49           translation performance.  Normally you want the VHPT active but you
  50           can select this option to disable the VHPT for debugging.  If you're
