2.5.47-ac5:undefined reference to `boot_gdt_table'

2.5.47-ac5:undefined reference to `boot_gdt_table'

[Gregoire Favre]

Hello,

I can't compil it:

  	ld -m elf_i386 -e stext -T arch/i386/vmlinux.lds.s arch/i386/kernel/head.o arch/i386/kernel/init_task.o  init/built-in.o --start-group  usr/built-in.o  arch/i386/kernel/built-in.o  arch/i386/mm/built-in.o  arch/i386/mach-generic/built-in.o  kernel/built-in.o  mm/built-in.o  fs/built-in.o  ipc/built-in.o  security/built-in.o  crypto/built-in.o  drivers/built-in.o  sound/built-in.o  arch/i386/pci/built-in.o  net/built-in.o  lib/lib.a  arch/i386/lib/lib.a --end-group  -o .tmp_vmlinux1
arch/i386/kernel/built-in.o(.data+0x15a5): In function `gdt_48':
: undefined reference to `boot_gdt_table'
make: *** [.tmp_vmlinux1] Error 1

Should I provide other infos?
Sorry if that was already reported and I didn't notice it...

	Grégoire

I think this is because -ac5 has X86_TRAMPOLINE dependent on X86_LOCAL_APIC.  
If you change

config X86_TRAMPOLINE
	bool
	depends on SMP || (VOYAGER && SMP) || X86_LOCAL_APIC

to

	depends on SMP

in arch/i386/Kconfig

does this fix the problem?

Alan: I'm just getting -ac5 up and running on voyager now, so I'll send in 
this as part of the rebased patches.

Worked here, at least.
