* master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6:
  [EBTABLES]: Clean up vmalloc usage in net/bridge/netfilter/ebtables.c
  [NET]: Add skb->truesize assertion checking.
  [TCP]: Account skb overhead in tcp_fragment
  [SUNGEM]: Marvell PHY suspend.
  [LLC]: Use pskb_trim_rcsum() in llc_fixup_skb().
  [NET]: sockfd_lookup_light() returns random error for -EBADFD
