s390/numa: always use logical cpu and core ids
The toptree algorithm uses the physical core ids to create a mapping between cores and nodes (to_node_id array within emu_cores structure). The core ids are used as an index into an array which size depends on CONFIG_NR_CPUS. If the physical core ids are larger, this will result in out-of-bounds write accesses. Generate logical core ids instead to avoid this. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
