* 'for-linus' of git://git.linux-nfs.org/projects/trondmy/nfs-2.6: (58 commits)
  SUNRPC: Ensure IPV6_V6ONLY is set on the socket before binding to a port
  NSM: Fix unaligned accesses in nsm_init_private()
  NFS: Simplify logic to compare socket addresses in client.c
  NFS: Start PF_INET6 callback listener only if IPv6 support is available
  lockd: Start PF_INET6 listener only if IPv6 support is available
  SUNRPC: Remove CONFIG_SUNRPC_REGISTER_V4
  SUNRPC: rpcb_register() should handle errors silently
  SUNRPC: Simplify kernel RPC service registration
  SUNRPC: Simplify svc_unregister()
  SUNRPC: Allow callers to pass rpcb_v4_register a NULL address
  SUNRPC: rpcbind actually interprets r_owner string
  SUNRPC: Clean up address type casts in rpcb_v4_register()
  SUNRPC: Don't return EPROTONOSUPPORT in svc_register()'s helpers
  SUNRPC: Use IPv4 loopback for registering AF_INET6 kernel RPC services
  SUNRPC: Set IPV6ONLY flag on PF_INET6 RPC listener sockets
  NFS: Revert creation of IPv6 listeners for lockd and NFSv4 callbacks
  SUNRPC: Remove @family argument from svc_create() and svc_create_pooled()
  SUNRPC: Change svc_create_xprt() to take a @family argument
  SUNRPC: svc_setup_socket() gets protocol family from socket
  SUNRPC: Pass a family argument to svc_register()
