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

Hi Andrew,

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

bench/numa.c: In function 'bind_to_node':
bench/numa.c:301:21: error: 'NUMA_NO_NODE' undeclared (first use in this function); did you mean 'NUMA_NUM_NODES'?
  if (target_node == NUMA_NO_NODE) {
                     ^~~~~~~~~~~~
                     NUMA_NUM_NODES
bench/numa.c:301:21: note: each undeclared identifier is reported only once for each function it appears in
bench/numa.c: In function 'bind_to_memnode':
bench/numa.c:342:14: error: 'NUMA_NO_NODE' undeclared (first use in this function); did you mean 'NUMA_NUM_NODES'?
  if (node == NUMA_NO_NODE)
              ^~~~~~~~~~~~
              NUMA_NUM_NODES
bench/numa.c: In function 'init_thread_data':
bench/numa.c:1366:19: error: 'NUMA_NO_NODE' undeclared (first use in this function); did you mean 'NUMA_NUM_NODES'?
   td->bind_node = NUMA_NO_NODE;
                   ^~~~~~~~~~~~
                   NUMA_NUM_NODES

Caused by commit

  3856193d8452 ("tools/: replace open encodings for NUMA_NO_NODE")

[BTW, I did not write that patch, just added fixes last time]
[BTW 2, there are lots of cc's that probably no longer apply since this
was split form the previous patch]

I have applied the following fix patch:
