Thanks, and sorry about that (I did test hsa/rocm only). I am reverting the change for now (it is being tested).

This change caused GPU hangs when running the piglit OpenCL tests using
the Mesa radeonsi driver on Bonaire, via the clover state tracker. Below
is an example of a GPUVM fault which accompanies the hang.
I'm afraid I don't have time to dig further.
