per-cpu alloc info (broken)

FWIW, I pulled out the per-cpu alloc info and what looks like the caller for
each (attached).  The big chunks look like IOMMU and iptables stuff.

This is from the 4.18 kernel with the problem.  Maybe we'd learn something by
collecting the same info from the working 4.17 kernel and comparing?

I wonder if there's some config difference that could be relevant?  Could you
attach the .config files for 4.17 and 4.18?
