Dear Stable Team,

This is a backport of ddbd89deb7d3 ("swiotlb: fix info leak with
DMA_FROM_DEVICE") and aa6f8dcbab47 ("swiotlb: rework "fix info leak with
DMA_FROM_DEVICE"") to 5.10.y.  

I had to handle some merge conflicts, and at this point we have
swiotlb_tbl_sync_single() as opposed to swiotlb_sync_single_for_device()
so I had to handle that as well.

Halil Pasic (2):
  swiotlb: fix info leak with DMA_FROM_DEVICE
  swiotlb: rework "fix info leak with DMA_FROM_DEVICE"
