From e3c495c74bc008a5c3671bf3411bc7f5382fa58f Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Wed, 9 Nov 2011 12:31:15 +0100 Subject: iommu/amd: Add driver stub for AMD IOMMUv2 support Add a Kconfig option for the optional driver. Since it is optional it can be compiled as a module and will only be loaded when required by another driver.
