* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: iwlwifi: Allow building iwl3945 without iwl4965. wireless: Fix compile error with wifi & leds tcp: Fix slab corruption with ipv6 and tcp6fuzz ipv4/ipv6 compat: Fix SSM applications on 64bit kernels. [IPSEC]: Use digest_null directly for auth sunrpc: fix missing kernel-doc can: Fix copy_from_user() results interpretation Revert "ipv6: Fix typo in net/ipv6/Kconfig" tipc: endianness annotations ipv6: result of csum_fold() is already 16bit, no need to cast [XFRM] AUDIT: Fix flowlabel text format ambibuity.
