[PATCH] x86_64: Use local APIC ID from local APIC instead of CPUID
vSMPowered systems use apic_cluster too. Forcing apic_physflat works on these systems too, but only if we change phys_pkg_id to use hard_smp_prcoessor_id() instead of cpuid_ebx. I am guessing other multichassi cluster systems would need this too.
