Every architecture that supports NUMA defines node_data in the same way:
struct pglist_data *node_data[MAX_NUMNODES];
No reason to keep multiple copies of this definition and its forward
declarations, especially

Make definition of node_data match other architectures.
This will allow pulling declaration of node_data to the generic mm code in

Below is a patch for a kretprobe-related problem that was already fixed
in v6.7 as a side-effect of the objpool optimization, in commit

I'm sending it to the list because it might be useful to pick the fix up

This is relatively small.
I had to drop a buggy commit in the middle so some hashes
