From 79a986721decf428ba539e6e2c941c987acce655 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 25 Jun 2019 11:20:42 +0200 Subject: dma-mapping: remove dma_max_pfn These days, the DMA mapping code must bounce buffers for any unsupported address. If the driver needs to optimize for natively supported ranges, then it should use dma_get_required_mask.
