patch 1 & 2 suppress unwanted memory allocation for net->gen->ptr[].

patch 3 ~ 6 move part of netns initialisation to prenet_init() that
do not reqruire pernet_ops_rwsem.


Kuniyuki Iwashima (6):
  l2tp: Don't assign net->gen->ptr[] for pppol2tp_net_ops.
  net: Don't register pernet_operations if only one of id or size is
    specified.
  net: Initialise net->passive once in preinit_net().
  net: Call preinit_net() without pernet_ops_rwsem.
  net: Slim down setup_net().
  net: Initialise net.core sysctl defaults in preinit_net().
