[Po-Hsu Lin]

Issue found with J-generic-5.15.0-88.98 on Openstack ppc64el instance.

After the ubuntu_bpf build issue (bug 2035181) fixed, test in ubuntu_bpf can be tested and reporting failures. There are 48 failures reported on this instance.

The failures are identical to J-arm64k, which failed with 47 test cases.
One extra failure in J-ppc64el is:
#144/p bpf_get_task_stack return R0 range is refined FAIL
