Merge patch series "treewide, numa_memblks: remove redundant work during NUMA init"

Sang-Heon Jeon <ekffu200098@gmail.com> says:

Every existing numa_add_memblk() caller passes a valid node id and
separately marks that node in numa_nodes_parsed with node_set(). In
addition, numa_nodemask_from_meminfo() recomputes the same "nodes that own
memory" set from numa_meminfo, which numa_nodes_parsed already contains.

This redundancy implicitly depends on the callers' node_set(). So, before
removing the redundancy, make numa_add_memblk() set the node in
numa_nodes_parsed explicitly. Then remove the per-caller node_set() and
numa_nodemask_from_meminfo().

Also, since the generic numa_register_meminfo() already sets
node_possible_map to numa_nodes_parsed, remove the duplicate assignment in
arch_numa's numa_register_nodes().
