There's a new patch bcm-lpae which uses the 64-bit page table format to allow 32-bit ARM kernels to support more than 4GB of physical memory. At present this is mainly of interest for the 8GB Raspberry Pi 4, but there's nothing Pi-specific in the MMU code so it may have future application for bigger ARM systems.
