See http://www.infradead.org/rpr.html Subject: [Xen-devel] [PATCH 13/13] arm64: use asm-generic/dma-mapping.h X-BeenThere: xen-devel@lists.xenproject.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , Cc: x86@kernel.org, linux-kernel@vger.kernel.org, iommu@lists.linux-foundation.org, xen-devel@lists.xenproject.org, Will Deacon , linux-arm-kernel@lists.infradead.org Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" Now that the Xen special cases are gone nothing worth mentioning is left in the arm64 file, so switch to use the asm-generic version instead.
