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://git.infradead.org/users/hch/misc.git swiotlb-noncoherent.2
Gitweb:
http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/swiotlb-noncoherent.2
Changes since v1: - make sure arm64 always calls dma_direct_alloc_pages to avoid circular calling conventions - add a patch in to stop dipping into the swiotlb pool for coherent allocations - this just depletes the swiotlb pool for no good reason
