The external module hackball should detect that you don't have
CONFIG_MMU_NOTIFIERS set and supply some compatibility glue. What
error are you seeing?
Basically struct mmu_notifier is not found, but requested by the code:

When I remove the struct references it breaks later on due to
missing(?) inline functions.
