[GIT PULL] dma-mapping updates for 5.8, part 2

[Christoph Hellwig]

These were in a separate stable branch so that various media and drm
trees could pull the in for bug fixes, but looking at linux-next that
hasn't actually happened yet.  Still sending the APIs to you in the
hope that these bug fixes get picked up for 5.8 in one way or another.
