This restores the behavior prior to 258f669e7e88 ("mm:
/proc/pid/smaps_rollup: convert to single value seq_file"), making it
once again consistent with maps and smaps, and allowing patterns like
awk '$1=="Anonymous:"{x+=$2}END{print x}' /proc/*/smaps_rollup to work.
Searching all Debian packages for "smaps_rollup" did not find any
programs which would be affected by this change.
Fixes: 258f669e7e88 ("mm: /proc/pid/smaps_rollup: convert to single value seq_file")
