v4: done changes as per Arnd review comments. v3: Added changes to support numa on arm64 based platforms. Tested these patches on cavium's multinode(2 node topology) platform. In this patchset, defined and implemented dt bindings for numa mapping for core and memory using device node property arm,associativity. v2: Defined and implemented numa map for memory, cores to node and proximity distance matrix of nodes to each other. v1: Initial patchset to support numa on arm64 platforms. Hi Arnd, there are not many common functions to pull to of driver from powerpc and arm. thanks Ganapat Ganapatrao Kulkarni (4): arm64: defconfig: increase NR_CPUS range to 2-4096.
