To distinguish the number of the memory tiering promoted pages from
that of the originally inter-socket NUMA balancing migrated pages.
The counter is per-node (count in the target node).  So this can be
used to identify promotion imbalance among the NUMA nodes.

I'd like this patch be the very first one in the series. Since we need
such counters regardless of all the optimizations. And actually I
think this patch could go with the merged "migration in lieu of
discard" patchset.

Yes.  This sounds reasonable.  I will change this in the next version.
