The non-server parts are quite available these days. I'm typing on one
right now:

model name : 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz

This can probably say:

Protection Keys for Userspace (PKU) can be found on:
* Intel server CPUs, Skylake and later
* Intel client CPUs, Tiger Lake (11th Gen Core) and later
* Future AMD CPUs

It would be great if the AMD folks can elaborate on that a bit, but I
understand it might not be possible if the CPUs aren't out yet.
