x86/amd-iommu: Flush all internal TLBs when IOMMUs are enabled
The old code only flushed a DTE or a domain TLB before it is actually used by the IOMMU driver. While this is efficient and works when done right it is more likely to introduce new bugs when changing code (which happened in the past). This patch adds code to flush all DTEs and all domain TLBs in each IOMMU right after it is enabled (at boot and after resume). This reduces the complexity of the driver and makes it less likely to introduce stale-TLB bugs in the future. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
