* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/net-2.6: (41 commits)
  [XFRM]: Fix leak of expired xfrm_states
  [ATM]: [he] initialize lock and tasklet earlier
  [IPV4]: Remove bogus ifdef mess in arp_process
  [SKBUFF]: Free old skb properly in skb_morph
  [IPV4]: Fix memory leak in inet_hashtables.h when NUMA is on
  [IPSEC]: Temporarily remove locks around copying of non-atomic fields
  [TCP] MTUprobe: Cleanup send queue check (no need to loop)
  [TCP]: MTUprobe: receiver window & data available checks fixed
  [MAINTAINERS]: tlan list is subscribers-only
  [SUNRPC]: Remove SPIN_LOCK_UNLOCKED
  [SUNRPC]: Make xprtsock.c:xs_setup_{udp,tcp}() static
  [PFKEY]: Sending an SADB_GET responds with an SADB_GET
  [IRDA]: Compilation for CONFIG_INET=n case
  [IPVS]: Fix compiler warning about unused register_ip_vs_protocol

  [IPV6] TCPMD5: Fix deleting key operation.
  [IPV6] TCPMD5: Check return value of tcp_alloc_md5sig_pool().
  [IPV4] TCPMD5: Use memmove() instead of memcpy() because we have overlaps.
  [IPV4] TCPMD5: Omit redundant NULL check for kfree() argument.
