Really a question for the ACPI folks, but my preferences would be:
- Simpler name for the interface, e.g., "acpi_get_cpu_id()"
- Single prototype in generic header, e.g., include/linux/acpi.h
- Split the x86 part to a separate patch and maybe (a tangent, but
looks dubious to me) figure out whether/why xen needs xen_vcpu_id
to be ACPI CPU IDs
