Hi all,

this series starts with various swiotlb cleanups, then adds support for
non-cache coherent devices to the generic swiotlb support, and finally
switches arm64 to use the generic code.

Given that this series depends on patches in the dma-mapping tree, or
pending for it I've also published a git tree here:

    git:// swiotlb-noncoherent
