  * check to see if #BR occurred in userspace or kernel space.
  * use generic structure and macro as much as possible when
    decode mpx instructions.

  x86, mpx: add documentation on Intel MPX
  x86, mpx: hook #BR exception handler to allocate bound tables
  x86, mpx: add prctl commands PR_MPX_INIT, PR_MPX_RELEASE
  x86, mpx: extend siginfo structure to include bound violation
