I'm trying to implement based on the feedback, but I'm a little confused.
As I have it at the moment, HMEM_REPORTING is not user-prompted, so
another option needs to turn it on. I have ACPI_HMAT do that here.
So when you say it's a bad idea to make HMEM_REPORTING user selectable,
isn't it already not user selectable?
If I do it the other way around, that's going to make HMEM_REPORTING
complicated if a non-ACPI implementation wants to report HMEM
properties.
