Experience with the existing /proc/cpuinfo shows that this needs *very* careful review. I've worked on arm64's /proc/cpuinfo, and I'd appreciate being Cc'd on future postings of this series. I'd also recommend that future postings are also Cc'd to linux-arch (and maybe linux-api) so that the interface is reviewed by a larger set of relevant parties. Thanks, Mark.
