This is v3 patch set 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.
Ganapatrao Kulkarni (4):
arm64: defconfig: increase NR_CPUS range to 2-4096.
