Hi Jack,

Can you please elaborate why this is required? AFAIK nowhere in the ACPI
spec does it say you need to order by big-little cores.
Is this some sort of regression for a specific OS? A useful commit message
and/or some comments would be really useful here for posterity.

Thanks,
Pedro Falcato
