From: "Mike Rapoport (Microsoft)" <rppt@kernel.org> numa_cleanup_meminfo() moves blocks outside system RAM to numa_reserved_meminfo and it uses 0 and PFN_PHYS(max_pfn) to determine the memory boundaries. Replace the memory range boundaries with more portable memblock_start_of_DRAM() and memblock_end_of_DRAM().
