Subject: linux-next: build failure after merge of the akpm tree

Hi Andrew,

After merging the akpm tree, today's linux-next build (powerpc_le perf)
failed like this:

bench/numa.c:37:10: fatal error: linux/numa.h: No such file or directory
 #include <linux/numa.h>
          ^~~~~~~~~~~~~~

Caused by patches

  "mm: replace all open encodings for NUMA_NO_NODE"
  "mm-replace-all-open-encodings-for-numa_no_node-fix"

For linux/numa.h to be generally availble to the tools builds, it must
be copied into tools/include/linux ...

I have done that copy for today:
