[PATCH] fix subarch breakage in amd dual core updates

[James Bottomley <James.Bottomley@SteelEye.com>]

The patch to arch/i386/kernel/cpu/amd.c relies on the variable
cpu_core_id which is defined in i386/kernel/smpboot.c.  This means it is
only present if CONFIG_X86_SMP is defined, not CONFIG_SMP (alternative
SMP harnesses won't have it, which is why it breaks voyager).
