2.5.37 : compile failed with undefined reference to find_smp_config with SMP disabled

2.5.37 : compile failed with undefined reference to find_smp_config with SMP disabled

[Alexis de Bernis]

	Hi,


	This happens with the vanilla 2.5.37 kernel. More information available
on demand.

Note : I have even more undefined reference with APIC enabled (and even, even more
with IO-APIC enabled).

The problem is that CONFIG_X86_FIND_SMP_CONFIG gets always enabled when you
enable APIC (CONFIG_X86_LOCAL_APIC).
