This support is found in kernels 2.6.35 and beyond. The new
affinity_hint hook found in /proc/irq/<num>/ can be populated
by underlying device drivers. The cpumask in this file will
be used as a preferred affinity, allowing devices with
multiple interrupt sources (e.g. MSI-X enabled network devices)
to better control their NUMA locality of data flows.
