OK, thank you :).
Notice that I did those tests on x86_64. It seems you are testing on arm, so there may be some differences.

I just checked these tests on 4.4.133 (on x86_64):
fcntl35: PASS
fcntl35_64: PASS
select04: PASS

I am currently investigating other tests that are failing as well. They are not regressions, just some patches have not been backported yet.

Thanks,
Daniel
