Subject: [PATCH bpf-next v2 3/4] selftests/bpf: Enable test_bpf_syscall_macro:syscall_arg1 on s390 and arm64
From: Pu Lehui <pulehui@...wei.com>
Considering that CO-RE direct read access to the first system call
argument is already available on s390 and arm64, let's enable
test_bpf_syscall_macro:syscall_arg1 on these architectures.
