From 905d66c1e5dc8149e111f04a32bb193f25da1d53 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Tue, 6 Sep 2011 16:03:26 +0200 Subject: iommu/core: Add bus_type parameter to iommu_domain_alloc This is necessary to store a pointer to the bus-specific iommu_ops in the iommu-domain structure. It will be used later to call into bus-specific iommu-ops.

This patch adds a bus_type parameter to that function and converts all call-places. The function is also renamed to iommu_present because the function now checks if an iommu is present for a given bus and does not check for a global iommu anymore.
