Subject: bpf: revert "test_bpf: Flag tests that cannot be jited on s390"
Patch-mainline: v5.9-rc1
Git-commit: de40a8abf07bfa125b7496b20ce6f92c6370eecd
References: bsc#1177028
This reverts commit 3203c9010060 ("test_bpf: flag tests that cannot
be jited on s390").
The s390 bpf JIT previously had a restriction on the maximum program
size, which required some tests in test_bpf to be flagged as expected
failures. The program size limitation has been removed, and the tests
now pass, so these tests should no longer be flagged.
Fixes: d1242b10ff03 ("s390/bpf: Remove JITed image size limitations")
