libbpf CI reported a bpf_syscall_macro test failure on s390 [1], which happens because the code uses gprs[2] instead of orig_gpr2 to access the first syscall argument. Patches 1-2 are preparations, patch 3 fixes the issue. @Heiko, @Vasily, @Christian, @Alexander - could you please review patch 1, which touches arch/s390? Would it be ok to put it into bpf-next tree?
