Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (82 commits) [NET]: Make sure sockets implement splice_read netconsole: avoid null pointer dereference at show_local_mac() [IPV6]: Fix reversed local_df test in ip6_fragment [XFRM]: Avoid bogus BUG() when throwing new policy away. [AF_KEY]: Fix bug in spdadd [NETFILTER] nf_conntrack_proto_tcp.c: Mistyped state corrected. net: xfrm statistics depend on INET [NETFILTER]: make secmark_tg_destroy() static [INET]: Unexport inet_listen_wlock [INET]: Unexport __inet_hash_connect [NET]: Improve cache line coherency of ingress qdisc [NET]: Fix race in dev_close(). (Bug 9750) [IPSEC]: Fix bogus usage of u64 on input sequence number [RTNETLINK]: Send a single notification on device state changes. [NETLABLE]: Hide netlbl_unlabel_audit_addr6 under ifdef CONFIG_IPV6. [NETLABEL]: Don't produce unused variables when IPv6 is off. [NETLABEL]: Compilation for CONFIG_AUDIT=n case. [GENETLINK]: Relax dances with genl_lock. [NETLABEL]: Fix lookup logic of netlbl_domhsh_search_def. [IPV6]: remove unused method declaration (net/ndisc.h). ...
