x86/amd-iommu: Export cache-coherency capability This patch exports the capability of the AMD IOMMU to force cache coherency of DMA transactions through the IOMMU-API. This is required to disable some nasty hacks in KVM when this capability is not available. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
