[PATCH] show Active/Inactive on per-node meminfo
The patch below enable to display the size of Active/Inactive pages on
per-node meminfo (/sys/devices/system/node/node%d/meminfo) like
/proc/meminfo.
By a little change to procps, "vmstat -a" can show these statistics about
particular node.

get_zone_counts() is used by max_sane_readahead(), and
max_sane_readahead() is often called in filemap_nopage().
