Thanks.  Wow I am out of it.  It appears that I was assuming elf_info
was zero initialized but taking no steps to make it that way, and
someone elf_info.get_note_info took the value of one.

I have added a memset and pushed that version of my code.
I also took a moment and made certain that kexec -p at least works.

I am surprised this bug didn't show up in my 32bit testing, *ugh*.

So if you are brave and want to test there is a slim chance my new
version of kexec will actually work on x86_64 now.
