Sugar sweet, you really need to say more than ping. You put the entire
recipient list in the To:, I have no idea what kind of feedback you
expect and from whom.

After switching cpumask to use nr_cpu_ids in [1], cpumask_check() started generating many false-positive warnings. There are some more issues with the cpumask_check() that brake it. This series fixes cpumask_check() mess and addresses most of the false-positive warnings observed on boot of x86_64 and arm64.
