This is the first time I've heard that there were still ongoing issues,
it's extremely disappointing - I'm guessing the attempts have all been
at the distro level.  Userspace fixes clearly aren't the thing to do
here, as discussed at the time the original fixes were done this is an
ABI and needs to be treated as such.

None of the systems I have access to have ever used topology so I've had
poor visibility of how this is working in practice, I guess I'm going to
start seeing this stuff next time I upgrade my laptop (unless someone is
making suitable non-x86 laptops by then!).

Thanks for doing this.  I'll give this some time for review from the
Intel people - adding Pierre as well since this is a bit of a device
thing.
