ACPI / scan: bail out early if failed to parse APIC ID for CPU
Enhance ACPI CPU hotplug driver to print clear error message and bail out early if BIOS returns wrong value in ACPI MADT table or _MAT method. Otherwise it will add the CPU device even if failed to get APIC ID and fails any operations against sysfs interface: /sys/devices/system/cpu/cpux/online Signed-off-by: Jiang Liu <jiang.liu@linux.intel.com> Signed-off-by: Rafael J.
