Lu Baolu e5e04d0519 iommu/vt-d: Check whether device requires bounce buffer ... This adds a helper to check whether a device needs to use bounce buffer. It also provides a boot time option to disable the bounce buffer. Users can use this to prevent the iommu driver from using the bounce buffer for performance gain.
