It's available on my laptop at least:

  $ egrep '^(model name|microcode)' /proc/cpuinfo | head -n2
  model name	: Intel(R) Core(TM) i7-6820HQ CPU @ 2.70GHz
  microcode	: 0x9e

  $ egrep -o ' (hle|rtm) ' /proc/cpuinfo | head -n2
   hle
   rtm

This is a mobile chip and an old stepping (and running the microcode that supposedly addresses the issue, presumably by disabling it on 'bad' chips?), so I'd be surprised if newer chips (especially server ones) didn't have it.

Hmm TIL. I think newer ones had an errata (or many) and Intel decided it wasn't worth fixing. Disappointing, but meh.. it is probably true that not many people use Tmem on laptops.
