      x86: PIE executable randomization · cc503c1b
      Jiri Kosina authored
      main executable of (specially compiled/linked -pie/-fpie) ET_DYN binaries
      onto a random address (in cases in which mmap() is allowed to perform a
      randomization).
      
      The code has been extraced from Ingo's exec-shield patch
      http://people.redhat.com/mingo/exec-shield/
