[David Tenty via Phabricator via llvm-commits]

daltenty added a comment.

> I don't think we can use HAVE_SYS_MMAN_H since this is defined on z/OS since we do have sys/mman.h header file. We just don't have madvise().

The version here now should provide the fallback for both the case where we the header isn't available or if we are on z/OS.
