Same feedback as in pxm_to_node export. No objections to exporting the symbol but it would be better to squash this function into the patch which uses it. The changelog is highly virtio-mem specific anyway. Maybe it is just a dejavu but I feel I have already said that but I do not remember any details. > Cc: Andrew Morton &lt...

One patch was reshuffled and two ACKs I missed to add were added. The rebase did not require any modifications to patches. Details about virtio-mem can be found in the cover letter of v2 [2]. A
