But the Kernel developers are heavily against the idea. Therefor, to the next idea: Parse in userspace. Turns out, there is a common tool almost everyone has installed does similar stuff. lscpu(1) from util-linux. So I proposed a patch to do ID mapping on arm/arm64 to util-linux, and it was accepted! So using lscpu from util-linux 2.32 (hopefully to be released soon) the above two systems look like:
