Hi Jesper,
I love your patch! Perhaps something to improve:

[also build test WARNING on v5.4-rc6 next-20191108]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

make C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'
If you fix the issue, kindly add following tag

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.
