* 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/net-2.6:
  [IRDA] IRNET: Fix build when TCGETS2 is defined.
  [NET]: docbook fixes for netif_ functions
  [NET]: Hide the net_ns kmem cache
  [NET]: Mark the setup_net as __net_init
  [NET]: Hide the dead code in the net_namespace.c
  [NET]: Relax the reference counting of init_net_ns
  [NETNS]: Make the init/exit hooks checks outside the loop
  [NET]: Forget the zero_it argument of sk_alloc()
  [NET]: Remove bogus zero_it argument from sk_alloc
  [NET]: Make the sk_clone() lighter
  [NET]: Move some core sock setup into sk_prot_alloc
  [NET]: Auto-zero the allocated sock object
  [NET]: Cleanup the allocation/freeing of the sock object
  [NET]: Move the get_net() from sock_copy()
  [NET]: Move the sock_copy() from the header
  [TCP]: Another TAGBITS -> SACKED_ACKED|LOST conversion
  [TCP]: Process DSACKs that reside within a SACK block
