Subject: [PATCH 01/10] iommu/core: Define iommu_ops and register_iommu only with CONFIG_IOMMU_API
Date: Fri, 23 Sep 2011 17:45:47 +0200 [thread overview]
Message-ID: <1316792756-3395-2-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1316792756-3395-1-git-send-email-joerg.roedel@amd.com>
This makes it impossible to compile an iommu driver into the
kernel without selecting CONFIG_IOMMU_API.
