3) Remove unused definitions in IPVS, also from YueHaibing.

4) Fix user data memleak in tables and objects, this is also amending
   a recent patch, from Jose M. Guisado.

5) Use nla_memdup() to allocate user data in table and objects, also
   from Jose M. Guisado

6) User data support for chains, from Jose M. Guisado

7) Remove unused definition in nf_tables_offload, from YueHaibing.

8) Use kvzalloc() in ip_set_alloc(), from Vasily Averin.
