-	  MPX provides hardware features that can be used in
-	  conjunction with compiler-instrumented code to check
-	  memory references.  It is designed to detect buffer
-	  overflow or underflow bugs.
-
-	  This option enables running applications which are
-	  instrumented or otherwise use MPX.  It does not use MPX
-	  itself inside the kernel or to protect the kernel
-	  against bad memory references.
-
-	  Enabling this option will make the kernel larger:
-	  ~8k of kernel text and 36 bytes of data on a 64-bit
-	  defconfig.  It adds a long to the 'mm_struct' which
-	  will increase the kernel memory overhead of each
-	  process and adds some branches to paths used during
-	  exec() and munmap().
