Hi Christoph
While backporting the patch I realised of a bug.

Thanks, with all the reviews in I've applied the series to the
dma-mapping tree for 5.13.
This will eventually become a stable baseline branch for the v4l work
and the mips drm driver that needs dma_mmap_pages, but I'd like to wait
a bit for any issues to pop up in linux-next first.

The timing is perfectly fine, I haven't even started the dma-mapping tree
for v5.13 yet.
Hi Christoph
I guess you can merge this patch from your tree. I hope it is not too
late in this release cycle.
Have a great week!

On architectures where there is no coherent caching such as ARM use the
dma_alloc_noncontiguous API and handle manually the cache flushing using
dma_sync_sgtable().
If the architechture has coherent cache, the API falls back to
alloc_dma_pages, so we can remove the coherent caching code-path from
8 matches
