Revision 5c94ac5d0f9e3c8791d1686e0bf22a2a341d1597 authored by Miaohe Lin on 18 October 2019, 02:50:31 UTC, committed by Paolo Bonzini on 22 October 2019, 16:47:50 UTC 
KVM: SVM: Fix potential wrong physical id in avic_handle_ldr_update
 
Guest physical APIC ID may not equal to vcpu->vcpu_id in some case.
We may set the wrong physical id in avic_handle_ldr_update as we
always use vcpu->vcpu_id. Get physical APIC ID from vAPIC page
instead.
Export and use kvm_xapic_id here and in avic_handle_apic_id_update
as suggested by Vitaly.
