It didn't revert cleanly on top of next-20190904, so I didn't get any further. Kevin [1] 419e2f1838819e954071dfa1d1f820ab3386ada1 is the first bad commit commit 419e2f1838819e954071dfa1d1f820ab3386ada1 Author: Christoph Hellwig Date: Mon Aug 26 09:03:44 2019 +0200 dma-mapping: remove arch_dma_mmap_pgprot arch_dma_mmap_pgprot is used for two things: 1) to override the "normal" uncached page attributes for mapping memory coherent to devices that can't snoop the CPU caches 2) to provide the special DMA_ATTR_WRITE_COMBINE semantics on older arm systems and some mips platforms Replace one with the pgprot_dmacoherent macro that is already provided by arm and much simpler to use, and lift the DMA_ATTR_WRITE_COMBINE handling to common code with an explicit arch opt-in.
