It is nice, but the other series are still impacted by the fsdax mess

I certainly would be unhappy if the amd driver, for instance, gained the fsdax problem as well and started pushing 4k pages into PMDs.
As said before: I think this all needs to be fixed. But I'd rather fix it gradually and I think this series is a nice step forward. After that we can look at the pte mappings.
Right, I agree with this
