Sorry, do you refer to JDK-8248238 (Implementation of JEP: Windows AArch64) or
to JDK-8253015 (Aarch64: Move linux code out from generic CPU feature
detection)?  Because first one was reviewed, but the second one (that is
included in the former) was not.

The intention of this CPU feature detection patch is to do a preparation and
make Windows/AArch64 patch more simple for review.

Could you and community review this (cpu feature detection) patch as well?

Thanks,
Anton
