There are inconsistencies between the command line using
"-numa node,cpus=XX" and what is checked internally:
the XX is supposed to be a CPU number, but for SPAPR
it's taken as a core number, ignoring the threads.
(See the description message of PATCH 1 for more details)

This series fixes this problem by introducing the threads
in the possible_cpus list instead of only the cores.
To avoid inconsistent topology, it doesn't allow anymore to
have an incomplete CPU NUMA config on the command line
(there was already a message announcing it will be absoleted
for 2 years).

Laurent Vivier (4):
  numa,spapr: add thread-id in the possible_cpus list
  numa: exit on incomplete CPU mapping
  numa: move cpu_slot_to_string() upper in the function
  numa: check threads of the same core are on the same node
