Subject: [PACTH v2 0/3] Implement /proc/<pid>/totmaps

From: Robert Foss <robert.foss@...labora.com>

This series implements /proc/PID/totmaps, a tool for retrieving summarized
information about the mappings of a process.

Changes since v1:
- Removed IS_ERR check from get_task_mm() function
- Changed comment format
- Moved proc_totmaps_operations declaration inside internal.h
- Switched to using do_maps_open() in totmaps_open() function,
  which provides privilege checking
- Error handling reworked for totmaps_open() function
- Switched to stack allocated struct mem_size_stats mss_sum in
  totmaps_proc_show() function
- Removed get_task_mm() in totmaps_proc_show() since priv->mm
  already is available
- Added support to proc_map_release() fork priv==NULL, to allow
  function to be used for all failure cases
- Added proc_totmaps_op and for it helper functions
- Added documention in separate patch
- Removed totmaps_release() since it was just a wrapper for
  proc_map_release()
