    vmalloc: lift the arm flag for coherent mappings to common code · fe9041c2
    Christoph Hellwig authored
    The arm architecture had a VM_ARM_DMA_CONSISTENT flag to mark DMA
    coherent remapping for a while.  Lift this flag to common code so
    that we can use it generically.  We also check it in the only place
    VM_USERMAP is directly check so that we can entirely replace that
    flag as well (although I'm not even sure why we'd want to allow
    remapping DMA appings, but I'd rather not change behavior).
