Subject: [PATCHv7 03/26] iommu/arm-smmu: add IOMMU_CAP_NOEXEC to the ARM SMMU driver
Date: Tue, 23 Sep 2014 16:46:02 +0200 [thread overview]
Message-ID: <1411483586-29304-4-git-send-email-a.motakis@virtualopensystems.com> (raw)
In-Reply-To: <1411483586-29304-1-git-send-email-a.motakis@virtualopensystems.com>
The ARM SMMU supports the IOMMU_NOEXEC protection flag. Add the
corresponding IOMMU capability.
