Subject: [PATCH v2 22/25] mm: numa_memblks: use memblock_{start,end}_of_DRAM() when sanitizing meminfo
From: "Mike Rapoport (Microsoft)" <rppt@...nel.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().
