The final 8 bits are the initial legacy APIC ID. For HVM guests, this was
overridden to vcpu_id * 2. The same logic is now applied to PV guests, so
guests don't observe a constant number on all vcpus via their emulated or
faulted view.

The features words, ecx and edx, are already audited as part of the featureset
logic. The existing leaf 0x8001 dynamic logic has its SYSCALL adjustment
split out, as the rest of the adjustments are common with leaf 0x1. The
existing leaf 0x1 feature adjustments from {pv,hvm}_cpuid() are moved
