Ilya Leoshkevich	490c99d4ed	selftests/bpf: Add UAF tests for arena atomics ... Check that __sync_*() functions don't cause kernel panics when handling freed arena pages. x86_64 does not support some arena atomics yet, and aarch64 may or may not support them, based on the availability of LSE atomics at run time. Do not enable this test for these architectures for simplicity.
