The next preliminary step to introduce NUMA FORM2 affinity is to make
the existing code independent of FORM1 macros and values, i.e.
MAX_DISTANCE_REF_POINTS, NUMA_ASSOC_SIZE and VCPU_ASSOC_SIZE. This patch
accomplishes that by doing the following:
- move the NUMA related macros from spapr.h to spapr_numa.c where they
are used. spapr.h gets instead a 'NUMA_NODES_MAX_NUM' macro that is used
to refer to the maximum number of NUMA nodes, including GPU nodes, that
the machine can support;
- MAX_DISTANCE_REF_POINTS and NUMA_ASSOC_SIZE are renamed to
FORM1_DIST_REF_POINTS and FORM1_NUMA_ASSOC_SIZE. These FORM1 specific
macros are used in FORM1 init functions;
- code that uses MAX_DISTANCE_REF_POINTS now retrieves the
max_dist_ref_points value using get_max_dist_ref_points().
NUMA_ASSOC_SIZE is replaced by get_numa_assoc_size() and VCPU_ASSOC_SIZE
is replaced by get_vcpu_assoc_size(). These functions are used by the
generic device tree functions and h_home_node_associativity() and will
allow them to switch between FORM1 and FORM2 without changing their core
logic.
