Re: [PATCH v7 10/14] arm64/numa: define numa_distance as array to simplify code

1. MAX_NUMNODES is base on CONFIG_NODES_SHIFT, the default value of the

2. Suppose the default value of MAX_NUMNODES is enlarged to 64, so the

   on other processors.
3. It will make function __node_distance quicker than before.

I fail to see the advantages of this patch. Do you have some compelling
performance figures or something?
