           However, the fixed address nature of these helpers can be used
           by ROP (return orientated programming) authors when creating
           exploits.
 
           If all of the binaries and libraries which run on your platform
           are built specifically for your platform, and make no use of
-          these helpers, then you can turn this option off.  However,

           Say N here only if you are absolutely certain that you do not
           need these helpers; otherwise, the safe option is to say Y.
