Christoph Hellwig 1f221a0d0d swiotlb: respect min_align_mask ... Respect the min_align_mask in struct device_dma_parameters in swiotlb. There are two parts to it: 1) for the lower bits of the alignment inside the io tlb slot, just extent the size of the allocation and leave the start of the slot empty 2) for the high bits ensure we find a slot that matches the high bits of the alignment to avoid wasting too much memory Based on an earlier patch from Jianxiong Gao <jxgao@google.com>.
