Using the interrupt affinity mask for checking locality is not really
working well on architectures which support effective affinity masks.

The affinity mask is either the system wide default or set by user

but the architecture can or even must reduce the mask to the
effective set,
which means that checking the affinity mask itself does not really
tell
about the actual target CPUs.
