Hi, i tried to cross compile arm/multi_v7_defconfig with CONFIG_XEN=y with Linux 5.3-rc5 and i'm getting this:
arch/arm/mm/dma-mapping.c: In function ‘arch_setup_dma_ops’: arch/arm/mm/dma-mapping.c:2347:5: error: ‘struct device’ has no member named ‘dma_coherent’ dev->dma_coherent = coherent; ^~ arch/arm/mm/dma-mapping.c: At top level: arch/arm/mm/dma-mapping.c:2385:6: error: redefinition of ‘arch_sync_dma_for_device’ void arch_sync_dma_for_device(struct device *dev, phys_addr_t paddr, ^~~~~~~~~~~~~~~~~~~~~~~~ In file included from arch/arm/mm/dma-mapping.c:18:0: ./include/linux/dma-noncoherent.h:67:20: note: previous definition of ‘arch_sync_dma_for_device’ was here static inline void arch_sync_dma_for_device(struct device *dev, ^~~~~~~~~~~~~~~~~~~~~~~~ arch/arm/mm/dma-mapping.c:2392:6: error: redefinition of ‘arch_sync_dma_for_cpu’ void arch_sync_dma_for_cpu(struct device *dev, phys_addr_t paddr, ^~~~~~~~~~~~~~~~~~~~~ In file included from arch/arm/mm/dma-mapping.c:18:0: ./include/linux/dma-noncoherent.h:77:20: note: previous definition of ‘arch_sync_dma_for_cpu’ was here static inline void arch_sync_dma_for_cpu(struct device *dev, ^~~~~~~~~~~~~~~~~~~~~ In file included from ./arch/arm/include/asm/page.h:149:0, from ./arch/arm/include/asm/thread_info.h:14, from ./include/linux/thread_info.h:38, from ./include/asm-generic/preempt.h:5, from ./arch/arm/include/generated/asm/preempt.h:1, from ./include/linux/preempt.h:78, from ./include/linux/spinlock.h:51, from ./include/linux/seqlock.h:36, from ./include/linux/time.h:6, from ./include/linux/stat.h:19, from ./include/linux/module.h:10, from arch/arm/mm/dma-mapping.c:9: There is no build issue with Linux 5.2, so this must be introduced with 5.3-rc. I hope you have a clue without bisecting this.
