====================
net: sysctl: allow dump_cpumask to handle higher numbers of CPUs

The main goal of this series is to allow dump_cpumask to handle higher
numbers of CPUs (patch 3). While doing so I had the opportunity to make
the function a bit simpler, which is done in patches 1-2.

None of those is net material IMO.
