		* QEMU comment:
		* FW_CFG_MAX_CPUS is a bit confusing/problematic
		* on x86:
		*
		* For machine types prior to 1.8, SeaBIOS needs
		* FW_CFG_MAX_CPUS for building MPTable, ACPI MADT,
		* ACPI CPU hotplug and ACPI SRAT table, that
		* tables are based on xAPIC ID and QEMU<->SeaBIOS
		* interface for CPU hotplug also uses APIC ID and
		* not "CPU index". This means that FW_CFG_MAX_CPUS
		* is not the "maximum number of CPUs", but the
		* "limit to the APIC ID values SeaBIOS may see".
		*
		* So for compatibility reasons with old BIOSes we
		* are stuck with "etc/max-cpus" actually being
		* apic_id_limit
