AMD IOMMU: add protection domain flags
Imapct: add a new struct member to 'struct protection_domain' When using protection domains for dma_ops and KVM its better to know for which subsystem it was allocated. Add a flags member to struct protection domain for that purpose. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
