I'm not sure how much this would help, but where I saw my red flag was
examining the objdump and seeing this:

  89:   bf 69 00 00 00          mov    $0x69,%edi
  8e:   e8 00 00 00 00          callq  93 <alternatives_smp_module_add+0x30>
                        8f: R_X86_64_PC32       .rodata+0x8c


A call to .rodata??
