v9: - Added cleanup patch to reuse and avoid redefinition of cpumask_of_pcibus
as suggested from Will Deacon and Bjorn Helgaas.
- Including patch to Make pci-host-generic driver numa aware.
- Incorporated comment from Shannon Zhao.
v8:
- Incorporated review comments of Mark Rutland and Will Deacon.
- Added pci helper function and macro for numa.
v7:
- managing numa memory mapping using memblock.
- Incorporated review comments of Mark Rutland.
v6:
- defined and implemented the numa dt binding using
node property proximity and device node distance-map.
- renamed dt_numa to of_numa
v5:
- created base verion of numa.c which creates dummy numa without using dt
on single socket platforms. Then added patches for dt support.
- Incorporated review comments from Hanjun Guo.
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.
v1:
Initial patchset to support numa on arm64 platforms.
Note:
1. This patchset is tested for numa with dt on
thunderx single socket and dual socket boards.
2. Numa DT booting needs the dt memory nodes, which are deleted in current efi-stub,
hence to try numa with dt, you need to rebase with ard's patchset.

3. PATCH 6 is not tested for other architectures.
