Re: use PCI layer IRQ affinity in lpfc

Hi Christoph,

We had already done this work in the larger lpfc patch that had been posted for nvme work.

I'll look at separating out just the irq part and post a reply.

This series has two patches: the first is a simple conversion of
lpfc to use pci_alloc_irq_vectors.  The second is more interesting,
and makes use of the PCI_IRQ_AFFINITY option to use the core interrupt
affinity assignment that takes nodes into account and can be easily
queried.  It also ensures we propagate this information to blk-mq
to make sure the block layer queues are properly aligned to the
interrupt vectors.

Note that these patches require core IRQ changes from a stable
branch in the tip tree to be pulled in first:

	git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq/for-block

Also be aware that I don't have any lpfc hardware to actually test these.
