From 8e3a68fb55e00e0760bd8023883e064f1f93c62d Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sat, 3 Aug 2019 12:42:15 +0300 Subject: dma-mapping: make dma_atomic_pool_init self-contained The memory allocated for the atomic pool needs to have the same mapping attributes that we use for remapping, so use pgprot_dmacoherent instead of open coding it. Also deduct a suitable zone to allocate the memory from based on the presence of the DMA zones.
