Subject: [PATCH v2 0/7] dma-mapping: Simplify arch_setup_dma_ops()
Date: Wed, 13 Dec 2023 17:17:53 +0000	[thread overview]
Message-ID: <cover.1702486837.git.robin.murphy@arm.com> (raw)

v1: https://lore.kernel.org/linux-iommu/cover.1701268753.git.robin.murphy@arm.com/

Hi all,

Here's v2 with a few tweaks and fixes to address review comments, a
couple of major issues fixed in the last two patches that I really
should have spotted initially, plus a bit more code deletion that I
realised could fit in this step. I've left it tagged as a dma-mapping
series since spiritually it still is, but it looks like it will want
to go via the IOMMU tree.

Thanks,
Robin.
