I was getting the error: map size mismatch; abort when running the daemon-conf tests. I traced it to two places in which we were passing a parameter as a number of bits to numa_node_to_cpus which expects a number of bytes (see numa_node_to_cpus_compat in numa.h in the numactl source). The attached patch fixes the problem.
