yes I haven't touched this part and I guess you are right it can be
removed now, but this was not my primary concern to adddress so there is
still some room for improvements on top. If you want to refactor that
part, then feel free to do so but I think that we should address the
MAP_FIXED part first.

Heh, I strongly suspect that this indirection is the last thing that
would make the code hard to grasp. The whole load_elf_binary is a giant
and incomprehensible mess.
