The patch below contains the following cleanups:
- make needlessly global code static
- remove the following unused global functions:
  - datagram.c: skb_copy_datagram
  - iovec.c: memcpy_tokerneliovec
- remove the following unneeded EXPORT_SYMBOL's:
  - datagram.c: skb_copy_datagram
  - dev.c: ing_filter
  - iovec.c: memcpy_tokerneliovec
  - netpoll.c: netpoll_send_skb
  - rtnetlink.c: rtnetlink_dump_ifinfo
  - sock.c: sock_alloc_send_pskb
