The migration of LPARs across Power systems affects many attributes
including that of the associativity of memory blocks.  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 recorded in
  internal data structures when compared to the latest copies in
  the device tree (e.g. ibm,dynamic-memory, ibm,dynamic-memory-v2).
* 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 memory.
* Re-register the 'changed' entities into the target system.
  Re-registration of memory blocks mostly entails acting as if they
  have been newly hot-added into the target system.

This code builds upon features introduced in a previous patch set
that updates CPUs for affinity changes that may occur during LPM.
