Fix for processors being offline on Arm
Use the number of configured rather than online CPUs.
We will still get a warning about failures when trying to
pin to offline CPUs, which hurts performance slightly.
To fix this, we also check if there is a mismatch between
configured and online processors and warn the user that
they should force all their processors online
for better performance.
