Patches 02 and 03 contain fixes for a problem Cedric found out when
booting TCG guests with multiple NUMA nodes. See patch 03 commit
message for more info.

This paragraph mentions "TCG guests", but I see nothing that is
specific to TCG in these patches... so I expect the problem to
also exists with KVM, right ?

Yeah. I mentioned TCG because this is the use case Cedric reproduced
the bug with, but I myself had no problems reproducing it with
accel=kvm as well.


First patch is an unrelated cleanup I did while investigating.

Daniel Henrique Barboza (3):
   spapr: move spapr_machine_using_legacy_numa() to spapr_numa.c
   spapr_numa.c: create spapr_numa_initial_nvgpu_NUMA_id() helper
   spapr_numa.c: fix ibm,max-associativity-domains calculation
