When comparing this to the MMU comments in include/asm-generic/unistd.h,
I noticed this:

M68knommu does have:
  - sys_mbind
  - sys_get_mempolicy
  - sys_set_mempolicy
  - sys_migrate_pages
  - sys_move_pages
  - sys_fork, although it returns -EINVAL, not -ENOSYS

M68knommu does not implement:
  - sys_mremap
  - sys_nfsservctl
