From: Christogh Hellwig <hch@xxxxxx> This is a variant of pci_alloc_irq_vectors() that allows passing a struct irq_affinity to provide fine-grainded IRQ affinity control. For now this means being able to exclude vectors at the beginning or end of the MSI vector space, but it could also be used for any other quirks needed in the future (e.g. more vectors than CPUs, or exluding CPUs from the spreading).
