* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (28 commits)
  ipheth: remove incorrect devtype to WWAN
  MAINTAINERS: Add CAIF
  sctp: fix test for end of loop
  KS8851: Correct RX packet allocation
  udp: add rehash on connect()
  net: blackhole route should always be recalculated
  ipv4: Suppress lockdep-RCU false positive in FIB trie (3)
  niu: Fix kernel buffer overflow for ETHTOOL_GRXCLSRLALL
  ipvs: fix active FTP
  gro: Re-fix different skb headrooms
  via-velocity: Turn scatter-gather support back off.
  ipv4: Fix reverse path filtering with multipath routing.
  UNIX: Do not loop forever at unix_autobind().
  PATCH: b44 Handle RX FIFO overflow better (simplified)
  irda: off by one
  3c59x: Fix deadlock in vortex_error()
  netfilter: discard overlapping IPv6 fragment
  ipv6: discard overlapping fragment
  net: fix tx queue selection for bridged devices implementing select_queue
  bonding: Fix jiffies overflow problems (again)
  ...

Fix up trivial conflicts due to the same cgroup API thinko fix going
through both Andrew and the networking tree.  However, there were small
differences between the two, with Andrew's version generally being the
nicer one, and the one I merged first. So pick that one.

Conflicts in: include/linux/cgroup.h and kernel/cgroup.c
