The patch looks good to me. one minor comment here. In an unlikely
scenario, valid_cpus which is a temporary mask can get allocated
but amu_fie_cpus may not. In that case, we have to free valid_cpus
here. I have seen some static code inspection tools catching these
type of errors. If you happen to rebase this series, fix this.

Thanks,
Pavan
