am 888d43b9: Merge remote-tracking branch \'toybox/master\' into HEAD

* commit '888d43b94f77ef2c1f126ef6099ee6fba454c682':

  vmstat: fix units for bi and bo columns
  Trivial code style tweak.
  vmstat: reset header pointer when looping
  ls -l user/group/security context should be left-aligned.
  Work around bug in gcc 5.2.0 that miscompiles linux 2.6.12's kconfig.
