OK, I see what you mean now. It's wrong indeed. The trouble is the ZONE_DMA series[1] in arm64, also due for v5.5, will be affected by this patch. I don't know the right way to approach this problem since depending on the merge order, this patch should be updated or the arm64 ZONE_DMA series fixed. Maybe it's easier to just wait for v5.6.Ok, I can wait. Or the arm64 maintainers can pick up this patch if you want to add it to that series.This branch is stable (may add a fix but not I'm not rebasing it) if you want to base this patch on top: https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/log/?h=for-next/zone-dma Otherwise, with your ack, I can add it on top of the above branch (aimed at 5.5).
