From 06ee6d571f0e350253a8fc3492316b2be007fae2 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 4 Jul 2016 17:39:24 +0900 Subject: genirq: Add affinity hint to irq allocation Add an extra argument to the irq(domain) allocation functions, so we can hand down affinity hints to the allocator. Thats necessary to implement proper support for multiqueue devices.
