v1: https://lore.kernel.org/bpf/[e-mail]/
v1 -> v2: Drop bpf_core_calc_field_relo() restructuring, split
          __BYTE_ORDER__ change.

Hi,

this series fixes test failures in core_reloc on s390.

Patches 1-4 replace __BYTE_ORDER with __BYTE_ORDER__ in order to fix an
endianness bug and make the code consistent.
Patch 5 fixes an endianness issue in test_core_reloc_mods.

Best regards,
Ilya
