Per the comment on the last patch, if compound dev_pagemap never
collides with vmem_altmap then I don't think this patch is needed.
See my previous patch reply. It *might* be worth keeping that around.
And since the RFC, nvdimm is going to need a slight adjustment for the
altmap reserve pfn range, should we keep altmap around.
