    arm64: Remove pgprot_dmacoherent() · 196adf2f
    Catalin Marinas authored
    Since this macro is identical to pgprot_writecombine() and is only used
    in a single place, remove it completely to avoid confusion. On ARMv7+
    processors, the coherent DMA mapping must be Normal NonCacheable (a.k.a.
    writecombine) to avoid mismatched hardware attribute aliases (with the
    kernel linear mapping as Normal Cacheable).
