Currently vlapic_build_id() uses vcpu_id to retrieve the lapic_id per_cpu variable: vlapic_id = per_cpu(lapic_id, vcpu->vcpu_id); SOS vcpu_id may not equal to pcpu_id, and in that case it runs into problems. For example, if any pre-launched VMs are launched on PCPUs whose IDs are smaller than any PCPU IDs that are used by SOS. This patch fixes the issue and simplify the code to create or get vapic_id by: - assign vapic_id in create_vlapic(), which now takes pcpu_id as input argument, and save it in the new field: vlapic->vapic_id, which will never be changed. - simplify vlapic_get_apicid() by returning te saved vapid_id directly. - remove vlapic_build_id(). - vlapic_init() is only called once, merge it into vlapic_create().
