Hi Nanhai,

I finally got a chance to look at this further.

Your patch touched four files:
    kexec/arch/ia64/kexec-elf-ia64.c
    purgatory/arch/ia64/entry.S
    purgatory/arch/ia64/include/arch/io.h
    purgatory/arch/ia64/io.h

I replaced both of the io.h with my version and it still
failed. So, it should be the way --noio option being handled
that made the difference.

I did have debug messages showing that "noio" option was
processed in elf_rel_set_symbol() in my testing. Does
kernel code need to know about this option? Somehow
this change makes kernel fail in init().

Thanks,
 - jay
