From: Jeremy Linton <redacted> Commit bbd1b70639f785a970d998f35155c713f975e3ac upstream. 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.

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! -- Thanks, Sasha _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
