ACPI Exception (): AE_NOT_FOUND, Processor Device is not present (update)
update cfaf3747ff3d431fba33f75083b7f50f58ae22ff
ACPI: ACPI Exception (): AE_NOT_FOUND, Processor Device is not present
is_processor_present is only called in the processor hotplug case,
and _STA method is mandatory at this time.
We should ignore those processors that are disabled in the MADT
and don't have _STA methods.
Because they will never exist in this system.
For the processors that don't physically exist but can be
hot plugged later, we still need this debug info.
