* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: [ISDN]: i4l: Fix DLE handling for i4l-audio [ISDN] i4l: 'NO CARRIER' message lost after ldisc flush [CONNECTOR]: Return proper error code in cn_call_callback() [INET]: Fix netdev renaming and inet address labels [CASSINI]: Bump driver version and release date. [CASSINI]: Fix two obvious NAPI bugs. [CASSINI]: Set skb->truesize properly on receive packets. [CASSINI]: Program parent Intel31154 bridge when necessary. [CASSINI]: Revert 'dont touch page_count'. [CASSINI]: Fix endianness bug. [XFRM]: Do not define km_migrate() if !CONFIG_XFRM_MIGRATE [X25]: Add missing x25_neigh_put
