Hi folks, Tariq pointed out in [1] that drivers allocating IRQ vectors would benefit from having smarter NUMA-awareness (cpumask_local_spread() doesn't quite cut it). The proposed interface involved an array of CPUs and a temporary cpumask, and being my difficult self what I'm proposing here is an interface that doesn't require any temporary storage other than some stack variables (at the cost of one wild macro). Patch 5/5 is just there to showcase how the thing would be used. If this doesn't get hated on, I'll let Tariq pick this up and push it with his networking driver changes (with actual changelogs).
I am interested in this work, but it seems that at least on lore and in my inbox, patch 3,4,5 didn't show up.
