Hi, The 1st patch makes __irq_build_affinity_masks() more reliable, such as, all nodes can be covered in the spread.
The 2nd patch spread vectors on node according to the ratio of this node's CPU number to number of all remaining CPUs, then vectors assignment can become more fair. Meantime, the warning report from Jon Derrick can be fixed. Please review & comment!
