[PATCH V2 0/3] powerpc/hotplug: Fix affinity assoc for LPAR migration

[Michael Bringmann]

The migration of LPARs across Power systems affects many attributes
including that of the associativity of memory blocks and CPUs.  The
patches in this set execute when a system is coming up fresh upon a
migration target.  They are intended to,

* Recognize changes to the associativity of memory and CPUs recorded
  in internal data structures when compared to the latest copies in
  the device tree (e.g. ibm,dynamic-memory, ibm,dynamic-memory-v2,
  cpus),
* Recognize changes to the associativity mapping (e.g. ibm,
  associativity-lookup-arrays), locate all assigned memory blocks
  corresponding to each changed row, and readd all such blocks.
* Generate calls to other code layers to reset the data structures
  related to associativity of the CPUs and memory.
* Re-register the 'changed' entities into the target system.
  Re-registration of CPUs and memory blocks mostly entails acting as
  if they have been newly hot-added into the target system.
