* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (27 commits)
  bnx2x: allow device properly initialize after hotplug
  bnx2x: fix DMAE timeout according to hw specifications
  bnx2x: properly handle CFC DEL in cnic flow
  bnx2x: call dev_kfree_skb_any instead of dev_kfree_skb
  net: filter: move forward declarations to avoid compile warnings
  pktgen: refactor pg_init() code
  pktgen: use vzalloc_node() instead of vmalloc_node() + memset()
  net: skb_trim explicitely check the linearity instead of data_len
  ipv4: Give backtrace in ip_rt_bug().
  net: avoid synchronize_rcu() in dev_deactivate_many
  net: remove synchronize_net() from netdev_set_master()
  rtnetlink: ignore NETDEV_RELEASE and NETDEV_JOIN event
  net: rename NETDEV_BONDING_DESLAVE to NETDEV_RELEASE
  bridge: call NETDEV_JOIN notifiers when add a slave
  netpoll: disable netpoll when enslave a device
  macvlan: Forward unicast frames in bridge mode to lowerdev
  net: Remove linux/prefetch.h include from linux/skbuff.h
  ipv4: Include linux/prefetch.h in fib_trie.c
  netlabel: Remove prefetches from list handlers.
  drivers/net: add prefetch header for prefetch users
  ...

Fixed up prefetch parts: removed a few duplicate prefetch.h includes,
fixed the location of the igb prefetch.h, took my version of the
skbuff.h code without the extra parentheses etc.
