The mediatek iommu driver relied on an implicit include of dma-mapping.h,
but for some reason that is no longer there in 4.12-rc1:
drivers/iommu/mtk_iommu_v1.c: In function 'mtk_iommu_domain_finalise':
drivers/iommu/mtk_iommu_v1.c:233:16: error: implicit declaration of function 'dma_zalloc_coherent'; did you mean 'debug_dma_alloc_coherent'? [-Werror=implicit-function-declaration]
drivers/iommu/mtk_iommu_v1.c: In function 'mtk_iommu_domain_free':
drivers/iommu/mtk_iommu_v1.c:265:2: error: implicit declaration of function 'dma_free_coherent'; did you mean 'debug_dma_free_coherent'? [-Werror=implicit-function-declaration]
This adds an explicit #include to make it build again.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
