The new rcu_read_lock test failed on s390x with the following error message: ... test_rcu_read_lock:PASS:join_cgroup /rcu_read_lock 0 nsec test_local_storage:PASS:skel_open 0 nsec libbpf: prog 'cgrp_succ': failed to find kernel BTF type ID of '__s390x_sys_getpgid': -3 libbpf: prog 'cgrp_succ': failed to prepare load attributes: -3 libbpf: prog 'cgrp_succ': failed to load: -3 libbpf: failed to load object 'rcu_read_lock' libbpf: failed to load BPF skeleton 'rcu_read_lock': -3 test_local_storage:FAIL:skel_load unexpected error: -3 (errno 3) ... It failed on aarch64 with the following error message due to inadequate trampoline support. ... test_rcu_read_lock:PASS:join_cgroup /rcu_read_lock 0 nsec test_local_storage:PASS:skel_open 0 nsec test_local_storage:PASS:skel_load 0 nsec libbpf: prog 'cgrp_succ': failed to attach: ERROR: strerror_r(-524)=22 libbpf: prog 'cgrp_succ': failed to auto-attach: -524 test_local_storage:FAIL:skel_attach unexpected error: -524 (errno 524) ... So add the test to s390x and aarch64 deny lists.
