Do you think GICC parameters are valid for an unusable processor?
Good point. We don't know if the value will be valid when the processor
is unusable.
If not we need a validation check here, some thing like this to skip
GICC subtable entry.
if (!(gicc->flags & ACPI_MADT_ENABLED))
return 0;
I will add this check.
