From da4689c0263ee5f4eee64e166a6bee6a68b9242e Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Tue, 27 Oct 2015 08:36:08 +0900 Subject: [PATCH] iommu/vt-d: Expose struct svm_dev_ops without CONFIG_INTEL_IOMMU_SVM The point in providing an inline version of intel_svm_bind_mm() which just returns -ENOSYS is that people are supposed to be able to *use* it and just see that it fails. So we need to let them have a definition of struct svm_dev_ops (and the flags) too.
