Things like "smep". But, things that the kernel "enables" but that only get used by userspace don't generally show up in /proc/cpuinfo. KVM is kinda a weird case. The kernel is making the feature available to guests, but it's not _using_ it in any meaningful way. To me, this seems much more akin to the features that are just available to userspace than something that the kernel is truly using. Also, these feature names are just long and ugly, and the "flags" line is already a human-*un*readable mess. I think we should just leave them out.
