I don't know if it's possible to see who contributed that patch (yet), but I’m cynical enough to half-expect that the “assume all x86 processors are insecure” patch might come from an Intel engineer...

I would not be surprised at all, considering the patch I saw for the AMD processors was literally a one-line if statement around the set cpu insecure flag that added a check for AMD processors.

Google is failing me or I'd post a link.

the patch was by Thomas Gleixner[0], who is not an Intel Engineer.

AMD has since pushed a patch to "not enable PTI on AMD processors" [1]
