Hello Dave,

I found something is missing in the committed patch. In dump_Elf64_Nhdr, qemu note of X86
is not available to call display_ELF_note. The process is like below:

if (BITS32() && type == NT_PRSTATUS)
	display_ELF_note
else
	if (machine_type("X86_64"))
		display_ELF_note

And about the fix, please check the attachment.
