[PATCH v3 0/7] pseries NUMA distance rework

[Daniel Henrique Barboza <danielhb413@gmail.com>]

Hi,

This spin attempts to cover all suggestions and concerns pointed
out by David Gibson in the v2 review.

The patches were rebased with David's ppc-for-5.2 at 615ae3763144.
They can also be cloned from
https://github.com/danielhb/qemu/tree/spapr_numa_v3.

Changes from v2:
- patches 1 and 2 from v2 -> already pushed to ppc-for-5.2
- patch 1 (former 3):
    * numa_assoc_array moved to SpaprMachineState
- patch 3 (former 5):
    * use memcpy
    * fix index increment to use MAX_DISTANCE_REF_POINTS
- patch 4 (former 6):
    * revamped. NVLink2 associativity is now calculated in
spapr_numa_associativity_init(). GPU code will use the same
helper everyone but vcpus uses to write the associativity DT
- patch 5 - new
- patch 6 - new
- patch 7:
    * no more brazilian portuguese notes in the commit message
    * change the code to handle an arbitrary vcpu associativity
array, retrieved with a new helper added by patch 6.
