Hi Michal,
I didn’t quite gut a question here. Do you mean scheduler affinity for offlined/not present CPUs?
From the patch, this message should be printed for every possible offlined node:
for_each_node(nid) {
...
if (!node_online(nid)) {
pr_warn("Node %d uninitialized by the platform. Please report with boot dmesg.\n", nid);
Thanks,
—Alexey
