Comment 2 for bug 1579205

The kernel I'm working on in unstable (git://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/unstable) will eventually become the Yakkety kernel. I've set NR_CPUS to 8K which is the default if you go above 512. I've already had a request to support a platform with over 1K cores. I'll leave it there unless we find through testing that it causes extraordinary RAM consumption or has some other deleterious side effect.
