This is the start of the stable review cycle for the 5.10.193 release.
There are 84 patches in this series, all will be posted as a response

let me know.

Responses should be made by Wed, 30 Aug 2023 10:11:30 +0000.
Anything received after that time might be too late.


FWIW, commit 619672bf2d04 ("MIPS: Alchemy: fix dbdma2") should be
reverted
v5.10.y since it doesn't fix anything but breaks the build for
affected boards
completely.

arch/mips/alchemy/common/dbdma.c: In function 'au1xxx_dbdma_put_source':
arch/mips/alchemy/common/dbdma.c:632:14: error:
'dma_default_coherent' undeclared

There is no 'dma_default_coherent' in v5.10.y.

But that was added in 5.10.185, from back in June. What changed to
suddenly cause this to fail now?


Nothing. I started to build this configuration and tracked down the
problem after the build failure was reported by others. Sorry, I didn't
initially realize that this is an old problem.

We could back port 6d4e9a8efe3d59f31367d79e970c2f328da139a4 ("driver
core: lift dma_default_coherent into common code") but that won't work
too well on 4.14 or 4.19. I believe it would be simpler to adjust the
branches with this patch, Manuel does that work?

Please drop this patch from all stable releases. I didn't CC stable
when I submitted it,
and have no idea why it ended up there anyway.
It was intended to fix a problem initially found in 5.18 (I think).

I'm going to revert it now, thanks!

I prepared reverts yesterday that I can send out if you want?
