Here's a few random minor cleanups I spotted while reviewing a few mm/*.c files.
No functional changes.

Luis Chamberlain (3):
  mm/show_mem: simplify ifdef on si_meminfo_node()
  mm/compaction: add and use for_each_populated_zone_pgdat() helper
  mm/vmstat: simplfy extfrag_show_print with fragmentation_index()

 include/linux/mmzone.h |  8 ++++++++
 mm/compaction.c        |  9 ++-------
 mm/show_mem.c          |  5 +----
 mm/vmstat.c            | 11 +++++------
