6.5-stable review patch. If anyone has any objections, please let me know.

commit e2de156b0d918b5ebe975577d25f9ef92379a756 upstream.
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.
