OK, here's the next bunch.  Sorry about the delay, iov_iter.c stuff
took most of the day (and it's not included in this pile).  Please, review.
Al Viro (17):
      new helper: skb_copy_and_csum_datagram_msg()
      new helper: memcpy_from_msg()
      switch ipxrtr_route_packet() from iovec to msghdr
      new helper: memcpy_to_msg()
      switch drivers/net/tun.c to ->read_iter()
      switch macvtap to ->read_iter()
      new helpers: skb_copy_datagram_from_iter() and zerocopy_sg_from_iter()
      {macvtap,tun}_get_user(): switch to iov_iter
      kill zerocopy_sg_from_iovec()
      switch AF_PACKET and AF_UNIX to skb_copy_datagram_from_iter()
      switch sctp_user_addto_chunk() and sctp_datamsg_from_user() to passing iov_iter
      tipc_sendmsg(): pass msghdr instead of its ->msg_iov
      tipc_msg_build(): pass msghdr instead of its ->msg_iov
      vmci_transport: switch ->enqeue_dgram, ->enqueue_stream and ->dequeue_stream to msghdr
      [atm] switch vcc_sendmsg() to copy_from_iter()
      rds: switch ->inc_copy_to_user() to passing iov_iter
      rds: switch rds_message_copy_from_user() to iov_iter

Patches themselves are in followups...
