    kernel - Make swap, nullfs MPSAFE
    
    * Mark the swap dummy mount as being MPSAFE so strategy operations do not
      acquire the mplock.
    
    * Mark NULLFS mounts as being MPSAFE so operations do not acquire the
      mplock.  If the underlying VFS is not MPSAFE it will still acquire
      the mplock.
