Subject: [PATCH v2 0/3] mm/shuffle: fix and cleanups

Patch #1 is a fix for overlapping zones and offline sections. Patch #2
documents why we have to shuffle on memory hotplug, when onlining memory.
Patch #3 removes dynamic reconfiguration which is currently dead code.

v1 -> v2:
- Replace "mm/memory_hotplug: don't shuffle complete zone when onlining
  memory" by "mm/memory_hotplug: document why shuffle_zone() is relevant"
- "mm/shuffle: remove dynamic reconfiguration"
-- Add details why autodetection is not implemented

David Hildenbrand (3):
  mm/shuffle: don't move pages between zones and don't read garbage
    memmaps
  mm/memory_hotplug: document why shuffle_zone() is relevant
  mm/shuffle: remove dynamic reconfiguration

 mm/memory_hotplug.c |  8 ++++++++
 mm/shuffle.c        | 46 +++++++++++----------------------------------
 mm/shuffle.h        | 17 -----------------
