Mike said that this should be fixed with
7d0e945584203a17ec0e1356bf9c873881893caf (kerndat: set uffd features to
0 before querying kernel), but I still get the same error on s390x if I
update to today's latest git: 

commit 0f867799e7e4b0fd5ea9677b8acaf51b18f78ce1

    zdtm/cgroup: Add test for ifpriomap


So something more is broken for me.
