ACPI 6.3 adds a flag to the CPU node to indicate whether
the given PE is a thread. Add a function to return that
information for a given linux logical CPU.

How far back should these patches be backported?
Hi Sasha,
This patchset is for 5.3, and I sent a separate patchset for 4.19,
since the backport is a little different and required some hand
modification -
https://lore.kernel.org/linux-arm-kernel/1571046986-231263-1-git-send-email-john.garry@xxxxxxxxxx/.
4.19 is as far back as we want.
Please note that the patches in this 5.3 series are relevant for 5.2
also, but since 5.2 is EOL, I didn't mention it. We did test 5.2, so
you can add there also.
Please let me know if any more questions.
I've queued this and the 4.19 patches, thanks!
