It's called a survey paper. In this case, the survey is particularly valuable, because the stuff in it was scattered across blog posts and conference presentations --- many of them by the author of the survey.
Just not a great critique going on in this subthread.

I think you're completely missing the point...the original title on HN did not have any of that information - it just said "Intel x86 considered harmful (new paper)". No context that it was a survey paper - initial impressions was that it was just another clickbait inflammatory article link.
The moderators rightfully changed it, which makes my criticism addressed & outdated.
