From 6d4e9a8efe3d59f31367d79e970c2f328da139a4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 10 Feb 2021 10:56:39 +0100 Subject: driver core: lift dma_default_coherent into common code Lift the dma_default_coherent variable from the mips architecture code to the driver core. This allows an architecture to sdefault all device to be DMA coherent at run time, even if the kernel is build with support for DMA noncoherent device. By allowing device_initialize to set the ->dma_coherent field to this default the amount of arch hooks required for this behavior can be greatly reduced.
