Hi Andrew, This is a miscellany of fixes and tweaks to the common DMA mapping code which I've been collecting. They don't strictly depend on each other, but I figure I may as well send them all together for the sake of explaining them in one place: #1 is a straightforward and hopefully obvious bugfix. #2 has been posted before but I subsequently forgot to follow up on it. It's still possible to hit this at least on arm64 systems, with the SWIOTLB/pl330 combination blowing up just running dmatest. #3 follows on from a recent discussion about dma_sync_sg[0]; there's already a related patch in -next from Sakari clarifying the docs. #4 seemed worth posting now that the recent rework means it no longer has to be a sprawling touch-all-the-architectures patch for something so small. Thanks, Robin.
