OK, I tried starting with this one.

The problem is that in the CONFIG_SWAP=n case, linux/swap.h uses these
functions.

These implicit declarations are bugs that should be fixed.

I tried adding an #include <linux/pagemap.h> to linux/swap.h, but this
broke things faster than I could fix them.

Does anyone know our header mess good enough for being able to help me
with this issue?
