[PATCH 4/4] irq: add support for allocating (and affinitizing) sets of IRQs

From: Jens Axboe A driver may have a need to allocate multiple sets of MSI/MSI-X interrupts, and have them appropriately affinitized. Add support for defining a number of sets in the irq_affinity structure, of varying sizes, and get each set affinitized correctly across the machine. Cc: Thomas
