AFAICT, we could save the wasted partial page in three ways: by trying
to link it first, if it's only a case of one file, by having a special

We already do the second of those for conventional data, so it would
make sense for percpu as well. Smarter linker would be better, but ugh,
I don't see that happening any time soon.
