      Description

      From Volker's comment in [1]: "[W]e still use the NUMA version 1 function prototypes (e.g."numa_node_to_cpus(int node, unsigned long *buffer, int buffer_len)" instead of "numa_node_to_cpus(int node, struct bitmask *mask)", but also "numa_interleave_memory()" and maybe others). I think we should switch all prototypes to the new NUMA version 2 interface"
