There is no need to define your own mmap(). Define NO_MMAP=1 in the
Makefile. Git already has its own fake mmap and knows how to write it
back to disk when making changes.
Or better to say: the fake mmap has functionality that is sufficient for
git. In particular, it does *not* write back changes to disk (it
supports only MAP_PRIVATE), and the mapped area does not change if the
file is changed by a third party.
