Some series of includes result in vma.h being imported by nommu under certain circumstances, which references FIRST_USER_ADDRESS and USER_PGTABLES_CEILING, neither of which are necessarily defined in a nommu scenario. Work around this by wrapping the inline function which references these (init_vma_munmap()) in an #ifdef CONFIG_MMU.
