Hm Ok. That's explainable. You don't have CONFIG_IA32_EMULATION set
and arch_setup_additional pages is only defined/exported in
syscall32.c which won't be built in your case. (It should go away if
you set CONFIG_IA32_EMULATION).
I think the easy and correct fix for this situation is defining
CONFIG_ARCH_HAS_SETUP_ADDITIONAL_PAGES on x86_64 only if
IA32_EMULATION is defined. (Because x86_64 proper doesn't seem to
require arch_setup_additional_pages() only IA32 emulation requires
it.)
The patch below should fix it. (Please use attachment - less chance of
whitespace issues. Sorry no control over mail client atm)
