With the flush queue the IOMMU TLBs will not be flushed at every dma-ops unmap operation. The unmapped ranges will be queued and flushed at once, when the queue is full. This makes unmapping operations a lot faster (on average) and restores the performance of the old address allocator. Signed-off-by:
