I am interested in making the x86 topology seen by guests more flexible.
This patch keeps the original functionality but allows the APIC identifier
seen by guests for each vCPU to be altered more easily in future revisions.

Since the same mapping of vcpu_id to vlapic id is currently preserved,
the existing adjustments for 'logical processors per package' are left unchanged.
