Unfortunately, I haven't been able to get any reviews on the following two patches: be2net: Use irq_update_affinity_hint hinic: Use irq_set_affinity_and_hint One option would be to proceed with the remaining patches and I can try posting these two again when I post patches for the remaining drivers? -- Thanks Nitesh
