Ok, I've created the new tree: git://git.infradead.org/users/hch/dma-mapping.git for-next Gitweb: http://git.infradead.org/users/hch/dma-mapping.git/shortlog/refs/heads/for-next And below is the patch to add the MAINTAINERS entry, additions welcome. Stephen, can you add this to linux-next? --- From 335979c41912e6c101a20b719862b2d837370df1 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 20 Jun 2017 11:17:30 +0200 Subject: MAINTAINERS: add entry for dma mapping helpers This code has been spread between getting in through arch trees, the iommu tree, -mm and the drivers tree. There will be a lot of work in this area, including consolidating various arch implementations into more common code, so ensure we have a proper git tree that facilitates cooperation with the architecture maintainers.
