Linus Torvalds 7007c89463 Reinstate some of "swiotlb: rework "fix info leak with DMA_FROM_DEVICE"" ... commit 901c7280ca upstream. Halil Pasic points out [1] that the full revert of that commit (revert in bddac7c1e0), and that a partial revert that only reverts the problematic case, but still keeps some of the cleanups is probably better.  And that partial revert [2] had already been verified by Oleksandr Natalenko to also fix the issue, I had just missed that in the long discussion. So let's reinstate the cleanups from commit aa6f8dcbab ("swiotlb: rework "fix info leak with DMA_FROM_DEVICE""), and effectively only revert the part that caused problems.
