If the swiotlb maps a multi-slab region, swiotlb_sync_single_range() can be invoked to sync a sub-region which does not include the first slab. Unfortunately io_tlb_orig_addr[] is only initialised for the first slab, and hence the call to sync_single() will read a garbage orig_addr in this case. This patch fixes the issue by initialising all mapped slabs in io_tlb_orig_addr[]. It also correctly adjusts the buffer pointer in sync_single() to handle the case that the given dma_addr is not aligned on a slab boundary.
