    kernel - Fix bug in x86-64 version of bzeront()
    
    * The x86-64 bzeront code was subtracting the wrong value from the count
      when looping.  Note that prior to this commit the code was not being
      used anyway.
    
    * Rearrange the way movnti support is detected and enable for x86-64.
