[RFC 0/3] acpi: cphp: add CPHP_GET_CPU_ID_CMD command to cpu hotplug MMIO interface

[Igor Mammedov]

As an alternative to passing to firmware topology info via new fwcfg files
so it could recreate APIC IDs based on it and order CPUs are enumerated,

extend CPU hotplug interface to return APIC ID as response to the new command
CPHP_GET_CPU_ID_CMD.
