Subject: [PATCH 14/14] dma-mapping: remove dma_max_pfn
Date: Tue, 12 Feb 2019 08:25:28 +0100 [thread overview]
Message-ID: <20190212072528.13167-15-hch@lst.de> (raw)
In-Reply-To: <20190212072528.13167-1-hch@lst.de>
These days the DMA mapping code must bounce buffer for any not supported
address, and if they driver needs to optimize for natively supported
ranged it should use dma_get_required_mask.
