Right the issue with validate_section_offset() is separate from the debug.
I will fix the pr_err warns first by tweaking the messages to not print
the variables that cause problems.

I will send a separate patch for validate_section_offset() which needs to
be arch specific similar to elf_check_arch().

Let me know if this plan sounds good.
