Merge branch 'line_info-check-for-ld_imm64'
Martin KaFai Lau says:
====================
This series ensures the line_info (passed by the userspace during
bpf_prog_load) cannot have its line_info.insn_off pointing to a
zero bpf insn code. F.e. a broken userspace tool might
generate a line_info.insn_off that points to the second
8 bytes of a BPF_LD_IMM64.
The first patch is the kernel change.
The second patch is a new test case.
