Subject: bpf: s390: add JIT support for bpf line info
Patch-mainline: v5.4-rc1
Git-commit: 53092f7e074936df43aa4dbf4b6c3df812f3dab9
References: bsc#1177028
This adds support for generating bpf line info for JITed programs
like commit 6f20c71d8505 ("bpf: powerpc64: add JIT support for bpf
line info") does for powerpc, but it should pass the array starting
from 1. This fixes test_btf.
