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.

This looks good.

Vs. merge logistics: I'm expecting some other changes in that area as per
discussion with megasas (IIRC) folks. So I'd like to apply that myself
right after -rc1 and provide it to you as a single commit to pull from so
we can avoid collisions in next and the merge window.
That sounds fine, thanks Thomas!
