Subject: [GIT PULL] dma-mapping updates for 5.10
Hi Linus,
please pull the dma-mapping update for 5.10. It contains a (clean) merge
of a later 5.9-rc commit, as I had to pull in a media subsystem revert
that is required for later commits.
There are a few trivial contextual conflicts due to the dma-mapping.h
split, for those simple keep both sides, that is the new headers added
by other trees as well as the ones added here, or the entire file
deletions in case of the arm tree.
The following changes since commit 171d4ff79f965c1f164705ef0aaea102a6ad238b:
Merge tag 'mmc-v5.9-rc4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc (2020-09-24 09:09:47 -0700)

ARM/ixp4xx: add a missing include of dma-map-ops.h (2020-10-13 13:28:22 +0200)
