Hi Jesper,

        make ARCH=x86_64 allmodconfig

If you fix the issue, kindly add following tag
Reported-by: kbuild test robot <lkp@intel.com>


sparse warnings: (new ones prefixed by >>)

>> net/core/page_pool.c:379:6: sparse: sparse: symbol 'page_pool_empty_alloc_cache_once' was not declared. Should it be static?

Please review and possibly fold the followup patch.
