Subject: [PATCH 13/34] powerpc/cell: use the generic iommu bypass code
Date: Wed, 14 Nov 2018 09:22:53 +0100 [thread overview]
Message-ID: <20181114082314.8965-14-hch@lst.de> (raw)
In-Reply-To: <20181114082314.8965-1-hch@lst.de>
This gets rid of a lot of clumsy code and finally allows us to mark
dma_iommu_ops const.
Signed-off-by: Christoph Hellwig <hch@lst.de>
