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

If you want bug fixes to land in 4.7, you'll need to base them on a
mainline kernel.

I heared that David Daney's acpi numa patch series was accepted and
put into next branch(Linux 4.8).
Otherwise I will suggest him sending his patch6-7 to mainline first.
So that, only a very small conflict will be exist.

I also tested that:
1. git am David Daney's patch6-7, then git am all of my patches on a
branch, named branch A.
2. git am David Daney's patch6-7 on another branch, named branch B.
3. when I git merge B into branch A, it's still conflict. So I guess
git merge is based on source code, rather than patches.

So at present, unless the maintainers are willing to resolve the
conflict, otherwise I update my patches will not work.

It usually depends on how complex the conflict is and whether your
patches functionally depend on the other patches. I have no idea what
the dependency is here since I haven't tried applying them to mainline.

Fortunately, these patches are not particularly urgent. So I think I
can wait until Linux 4.8 start, then send these patches again. But I'm
not sure whether these patches can be merged into Linux 4.8, I really
hope.

If there are fixes to the arm64 ACPI NUMA patches that Rafael queued
into linux-next, they should be sent to him and potentially being queued
on top ahead of the 4.8 merging window or shortly after 4.8-rc1.
Non-ACPI NUMA patches (as I can see, most of these patches are DT
specific) could be merged independently.

So how many patches do you have in each category below:

1. NUMA fixes against current mainline (4.7-rc3)
2. NUMA fixes against the arm64 ACPI NUMA patches queued by Rafael
3. New functionality or clean-up. Are these against mainline or ACPI
   NUMA patches?
