In the cgroup v1, we have a numa_stat interface. This is useful for
providing visibility into the numa locality information within an
memcg since the pages are allowed to be allocated from any physical
node. One of the use cases is evaluating application performance by
combining this information with the application's CPU allocation.
But the cgroup v2 does not. So this patch adds the missing information.

This is a feature patch, why does this have LKP's Reported-by?

In the v2 version, the kernel test robot reported a compiler error
on the powerpc architecture. So I added that. Thanks.
