// This code is broken on kernels with CONFIG_NR_CPUS >= 1024, since cpu_set_t
// is too small by default. See <http://trac.wildfiregames.com/ticket/547>.
// It seems the most reliable solution is to use dynamically-allocated sets
// (CPU_SET_S etc), and do it in a loop until we've allocated a set large
// enough to fit all the CPUs.
// That's a pain and we currently don't actually need this code at all, and on OS X
// we don't implement this function anyway, so just disable it here.
