Issues relating to a bug in Intel cpus

Intel's treatment of *BSD is frankly quite insulting, especially so given that they serve a _huge_ portion of the internet traffic, with Netflix using FreeBSD for content delivery.
To be honest the attitude of "everything sucks and everything is broken" doesn't help OpenBSD though they are right to complain about some things.
Well, looking at all the chips I've bought in servers for the last 5 years, they are not wrong.

What's funny is that LWN, a Linux news outlet, might have:
It may well be just one or two people doing it, but their actions are screwing things up for an entire set of operating systems.
It's especially critical for coordination to happen on vulnerabilities like this one, where it requires a combination of microcode and kernel patches to be done in sync. If one distribution leaks early, all are put at nearly immediate significant risk.
> We believe Intel cpus do almost no security checks up-front, but defer checks until instruction retire. As a result we believe similar issues will be coming in the future.
Most ARM & MIPS CPUs just don't yet have the raw power people have come to expect.
The core lesson appears to be that Intel has been playing loose with security. That is not a fundamental x86 problem, not so long as AMD is producing competent cpus.
