Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull core dump fix from Al Viro:
 "Fix for multithreaded coredump playing fast and loose with getting
  registers of secondary threads; if a secondary gets caught in the
  middle of exit(2), the conditition it will be stopped in for dumper to
  examine might be unusual enough for things to go wrong.

  Quite a few architectures are fine with that, but some are not."

* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  don't dump the threads that had been already exiting when zapped.
