In the Linux kernel, the following vulnerability has been resolved:  iommu/vt-d: Force requesting ACS when tboot is enabled  Currently the conditions of requesting ACS in detectinteliommu() don't include tboot, leading to a possible misconfiguration with ACS disabled (e.g. due to user opts) while iommu is later forced on by tbootforceiommu().  Fix it by checking tboot in detectinteliommu().
