Similar to arm64 and riscv, when using a modern compiler (!gcc4.2), code generated tries to access data in the wrong location, causing kernel panic (data storage interrupt trap) when loading if_epair and ipfw. Issue was reproduced with kernel/module compiled using gcc8 and clang8. It affects both ELFv1 and ELFv2 ABI environments.
