From mboxrd@z Thu Jan 1 00:00:00 1970 From: hch@lst.de (Christoph Hellwig) Date: Fri, 18 May 2018 15:45:40 +0200 Subject: [PATCH 1/6] dma-mapping: simplify Kconfig dependencies In-Reply-To: <20180518134545.5036-1-hch@lst.de> References: <20180518134545.5036-1-hch@lst.de> List-ID: Message-ID: <20180518134545.5036-2-hch@lst.de> To: linux-snps-arc@lists.infradead.org ARCH_DMA_ADDR_T_64BIT is always true for 64-bit architectures now, so we can skip the clause requiring it. 'n' is the default default, so no need to explicitly state it.
