Merge branch 'exec-linus' of git://git./linux/kernel/git/ebiederm/user-namespace

Pull execve fix from Eric Biederman:
 "While working on my exec cleanups I found a bug in exec that I
  introduced by accident a couple of years ago. I apparently missed the
  fact that bprm->file can change.

  Now I have a very personal motive to clean up exec and make it more
  approachable.

  The change is just moving woud_dump to where it acts on the final
  bprm->file not the initial bprm->file. I have been careful and tested
  and verify this fix works"
