I see Andrew has taken this into mm-unstable though, so my bad for not
getting around to following all this up sooner.

How would that work in practice though? The abstract

The other way (suggested by this series) is to make dax/kmem call a
notifier chain, then CXL CDAT or ACPI HMAT can identify the type of
device and calculate the distance if the type is correct for them. I
don't think that
