[PATCH v3 0/5] pseries NUMA distance calculation

[Daniel Henrique Barboza]

This third version is based on review comments and suggestion
from David.

changes from v2:
- patch 3 from v2: removed
- patch 2:
    * added David's R-b
- patch 3 (former 4 in v2):
    * added Greg and David R-bs
    * added G_STATIC_ASSERT() before memcpy()
- patch 4 (former 5 in v2):
    * clarified what 'node 0' means in the commit msg
    * rewrote a bit to clarify what the logic does
    * the translation of user distance to PAPR distance logic,
      previously presented in the former patch 3 in v2, was folded
      into spapr_numa_get_numa_level()
    * removed needless 'if' when assigning associativities in
      spapr_numa_define_associativity_domains()
- patch 5 (former 6 in v2):
    * moved the section describing the current logic up
    * created a new 'legacy' section describing the pre-5.2
      behavior
    * added a 'known limitations' section documentating that
      we don't support asymmetrical topologies and we do a poor
      job approximating 'non-transitive' topologies
