Bug description:
  This bug appears to be due to a regression of the fix for:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1450584

  Specifically, the edit history for
  https://github.com/torvalds/linux/commits/master/arch/x86/kernel/pvclock.c
  (one of the files that the parent mentioned needed patching for the
  fix) shows that the changes added for the fix were removed one month
  later.
