geopm_sched_woomp()

int geopm_sched_woomp	(	int	num_cpu,
		cpu_set_t *	woomp
	)

Function that returns a cpuset that has bits set for all CPUs enabled for the process which are not used by OpenMP. Rather than returning an empty mask, if all CPUs allocated for the process are used by OpenMP, then the woomp mask will have all bits set.
