This modification only related to patch 3, but impacted the contents of patch 7 and 8, other patches have no change. v4 -> v5: This version has no code changes, just add "Acked-by: Rob Herring " into patches 1, 2, 4, 6, 7, 13, 14. Because these patches rely on some acpi numa patches, and the latter had not been upstreamed in 4.7, but upstreamed in 4.8-rc1, so I resend my patches again. v3 -> v4: 1. Packed three patches of Kefeng Wang, patch6-8. 2. Add 6 new patches(9-15) to enhance the numa on arm64. v2 -> v3: 1. Adjust patch2 and patch5 according to Matthias Brugger's advice, to make the patches looks more well. The final code have no change. v1 -> v2: 1. Base on https://lkml.org/lkml/2016/5/24/679 2. Rewrote of_numa_parse_memory_nodes according to Rob Herring's advice. So that it looks more clear. 3. Rewrote patch 5 because some scenes were not considered before.
