 pointer mapping

Hi Jesper,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on net-next/master]

url:    https://github.com/0day-ci/linux/commits/Jesper-Dangaard-Brouer/XDP-redirect-memory-return-API/20180330-203122
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)

>> net/core/xdp.c:19:1: sparse: symbol 'mem_id_pool' was not declared. Should it be static?
>> net/core/xdp.c:68:6: sparse: symbol '__xdp_mem_allocator_rcu_free' was not declared. Should it be static?
>> net/core/xdp.c:87:6: sparse: symbol '__xdp_rxq_info_unreg_mem_model' was not declared. Should it be static?
>> net/core/xdp.c:177:5: sparse: symbol '__mem_id_init_hash_table' was not declared. Should it be static?

Please review and possibly fold the followup patch.
