    drm: add more MMU dependencies · f0c379a1
    Arnd Bergmann authored
    Many DRM drivers only work with an MMU, and after the patch to enable
    core DRM support without MMU, we already had one fixup for many of them.
    The etnaviv, armada and msm drivers were missed and have the same problem:
    
    warning: (DRM_ETNAVIV) selects IOMMU_SUPPORT which has unmet direct dependencies (MMU)
    warning: (DRM_I915 && DRM_MSM && DRM_ETNAVIV) selects SHMEM which has unmet direct dependencies (MMU)
    drivers/gpu/drm/armada/armada_gem.o: In function `armada_gem_vm_fault':
    armada_gem.c:(.text.armada_gem_vm_fault+0x14): undefined reference to `vm_insert_pfn'
    arch/arm/mm/dma-mapping.c: In function '__iommu_alloc_remap':
    arch/arm/mm/dma-mapping.c:1390:4: error: 'VM_ARM_DMA_CONSISTENT' undeclared (first use in this function)
    arch/arm/mm/dma-mapping.c:1456:31: error: 'atomic_pool' undeclared (first use in this function); did you mean 'atomic_xor'?
