Pull kcmp kconfig update from Daniel Vetter:
 "Make the kcmp syscall available independently of checkpoint/restore.

  drm userspaces uses this, systemd uses this, so makes sense to pull it
  out from the checkpoint-restore bundle.

  Kees reviewed this from security pov and is happy with the final
  version"
