======================================

* SLUB: slab order calculation refactoring (Vlastimil Babka, Feng Tang)

  Recent proposals to tune the slab order calculations have prompted us to
  look at the current code and refactor it to make it easier to follow and
  eliminate some odd corner cases. The refactoring is mostly non-functional
  changes, but should make the actual tuning easier to implement and review.

----------------------------------------------------------------
Feng Tang (1):
      mm/slub: add sanity check for slub_min/max_order cmdline setup

Vlastimil Babka (4):
      mm/slub: simplify the last resort slab order calculation
      mm/slub: remove min_objects loop from calculate_order()
      mm/slub: attempt to find layouts up to 1/2 waste in calculate_order()
      mm/slub: refactor calculate_order() and calc_slab_order()
