Subject: support range based offsets in dma-direct
Date: Thu, 10 Sep 2020 07:40:35 +0200 [thread overview]
Message-ID: <20200910054038.324517-1-hch@lst.de> (raw)
Hi all,
this series adds range-based offsets to the dma-direct implementation. The
guts of the change are a patch from Jim with some modifications from me,
but to do it nicely we need to ARM patches to prepare for it as well.
