* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6:
  net_cls: fix unconfigured struct tcf_proto keeps chaining and avoid kernel panic when we use cls_cgroup
  e1000: add missing length check to e1000 receive routine
  forcedeth: add phy_power_down parameter, leave phy powered up by default (v2)
  Bluetooth: Remove useless flush_work() causing lockdep warnings
