[PATCH v3 22/26] mm: numa_memblks: use memblock_{start,end}_of_DRAM() when sanitizing meminfo

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "Mike Rapoport (Microsoft)" <rppt@xxxxxxxxxx>

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().

Tested-by: Zi Yan <ziy@xxxxxxxxxx> # for x86_64 and arm64
