ACK.
That looks right, since it has to match arg2 of this:

  static inline int numa_node_to_cpus_compat(int node, unsigned long *buffer,
                                                          int buffer_len)

At first glance, I had doubts about using the sometimes-narrower type,
but all uses are scaled by "sizeof *mask", so if it weren't for that
prototype, any unsigned type would do.
