Subject: move the arm arch_dma_alloc implementation to common code
Date: Fri, 9 Nov 2018 08:52:38 +0100 [thread overview]
Message-ID: <20181109075238.GA27578@lst.de> (raw)
In-Reply-To: <20181105121931.13481-1-hch@lst.de>
Can I get a quick review from the arm64 folks? I think it should
be fine there as it basically is a code move, but an additional pair
or two of eyes always helps to weed out bugs.
