From 8638c4914f34fedc1c13b1cc13f6d1e5a78c46b4 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Thu, 10 Dec 2009 11:12:25 +0100 Subject: x86/amd-iommu: Fix PCI hotplug with passthrough mode The device change notifier is initialized in the dma_ops initialization path. But this path is never executed for iommu=pt. Move the notifier initialization to IOMMU hardware init code to fix this.
