Subject: selftests/mm: include mman header to access MREMAP_DONTUNMAP identifier
Date: Thu, 12 Oct 2023 08:52:57 -0700
Definition for MREMAP_DONTUNMAP is not present in glibc older than 2.32
thus throwing an undeclared error when running make on mm. Including
linux/mman.h solves the build error for people having older glibc.
