Matt,

I think it's fine that upstream has demoted the BUG_ON, as I haven't
heard anyone report this with a kernel later than 3.13; I assume
whatever is causing it is fixed in later kernels.

At this point there's not much more I can do, as I can't reproduce it
and don't have much debug info on exactly what/why the zone's pfn range
becomes incorrect.  If you or anyone has any info on how to reproduce
this, or you have a system where it's reproducable, please let me know.
