From d07c1be0693e0902d743160b8b638585b808f8ac Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Tue, 10 Nov 2009 19:46:12 +0900 Subject: x86: Add iommu_init to x86_init_ops We call the detections functions of all the IOMMUs then all their initialization functions. The latter is pointless since we don't detect multiple different IOMMUs. What we need to do is calling the initialization function of the detected IOMMU. This adds iommu_init hook to x86_init_ops so if an IOMMU detection function can set its initialization function to the hook.
