as far as I can tell, now for_each_populated_zone() iterations are
split by non-CONT printk() from show_zone_node(), which previously
has been   printk(KERN_CONT "%s: ", zone->name), so pr_cont(\n)
between iterations was important, but now that non-CONT printk()
should do the trick. it's _a bit_ hacky, though.

Do you consider that more hacky than the original?

well, slightly. merely because (to me) implicit always relies on
internals, which can change; while explicit does not (ideally).
simply because of that.

but I don't have any problems with your patch.
