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.
