Probably you should start to worry(or celebrate) about April next year, I don't see OpenCL being in any upstream usable form before beside I'm not sure yet if they will use HMM for OpenCL 2.1+ either.
Note: this article refers only to the current upstreamed code in 4.14, so is not like a declaration that it won't work with older hardware, is just what so far has landed is for the newer hardware.

The sheer lack of clarity from a professional standpoint is shotty, at best.
here comes a copy from Marek's post on mesa-devel about:

I can confirm with 100% certainty that PCIe 3.0 atomics aren't
required if you don't need them. In the majority cases, you don't need
them.
