[137003] VAR '_alloc_tag_cntr.5' type_id=703, linkage=static

...should give us a sense of what's going on. I only see 375 per-cpu
variables when I do this so maybe there's something
kernel-config-specific that might explain why you have so many more?

Yes, as mentioned earlier, this is specifically due to the .config.
The .config is a huge distro configuration that has a lot of modules
enabled.
