Comment (by waddlesplash):

Adding more ifdefs will make it even less readable

 Why do we need more ifdefs? It looks to me like we can use the Linux
 ifdefs and also activate them under Haiku.

Our implementation is not identical to Linux (it uses mprotect in places
 where we need mmap, so we can't reuse these paths).

 No, it uses mprotect correctly; in fact, it does exactly what mmlr's
 suggestions above are. It also calls madvise, too, but that's fine.
