From ed3119e45519880a246b085ba6a96aa1074da532 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Mon, 18 May 2020 14:08:55 +0200 Subject: [PATCH] x86: Hide the archdata.iommu field behind generic IOMMU_API There is a generic, kernel wide configuration symbol for enabling the IOMMU specific bits: CONFIG_IOMMU_API. Implementations (including INTEL_IOMMU and AMD_IOMMU driver) select it so use it here as well. This makes the conditional archdata.iommu field consistent with other platforms and also fixes any compile test builds of other IOMMU drivers, when INTEL_IOMMU or AMD_IOMMU are not selected). For the case when INTEL_IOMMU/AMD_IOMMU and COMPILE_TEST are not selected, this should create functionally equivalent code/choice. With COMPILE_TEST this field could appear if other IOMMU drivers are chosen but neither INTEL_IOMMU nor AMD_IOMMU are not.
