Hi Oleksandr. Wow 2013, thanks for doing the triage!

As John mentioned, the part about exposing them on linprocfs made sense. Since
I verified, it was implemented into sys/compat/linprocfs [1] with r317884 [2] 

As Konstantin mentioned, it might break something in the other tier
architectures and it's not really needed as we have already alternatives to
gather CPU information. 

Back in 2013, I remember my idea was to expose them through sysctl as MacOSX
does under machdep.cpu but we don't have this oid tree in FreeBSD.

I closed it.
