From 2ef75701d1711a1feee2a82b42a2597ddc05f88b Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 21 Jul 2011 14:51:13 +0100 Subject: ARM: CPU hotplug: fix abuse of irqdesc->node irqdesc's node member is supposed to mark the numa node number for the interrupt. Our use of it is non-standard. Remove this, replacing the functionality with a test of the affinity mask.
