Memory mapped I/O actually prevents the use of huge pages if the backing storage is an actual disk. See https://lwn.net/Articles/718102/

Do you know of a way around that, aside from building your own patched kernel?

Yeah you need to move your files to tmpfs, but I still consider that easier than dealing with making it happen with malloc+read
