#     Merge tag 'remove-dma_zalloc_coherent-5.0' of git://git.infradead.org/users/hch/dma-mapping
#     
#     Pull dma_zalloc_coherent() removal from Christoph Hellwig:
#      "We've always had a weird situation around dma_zalloc_coherent. To
#       safely support mapping the allocations to userspace major
#       architectures like x86 and arm have always zeroed allocations from
#       dma_alloc_coherent, but a couple other architectures were missing that
#       zeroing either always or in corner cases.
#     
#       Then later we grew anothe dma_zalloc_coherent interface to explicitly
#       request zeroing, but that just added __GFP_ZERO to the allocation
#       flags, which for some allocators that didn't end up using the page
#       allocator ended up being a no-op and still not zeroing the
#       allocations.
#     
#       So for this merge window I fixed up all remaining architectures to
#       zero the memory in dma_alloc_coherent, and made dma_zalloc_coherent a
#       no-op wrapper around dma_alloc_coherent, which fixes all of the above
#       issues.
#     
#       dma_zalloc_coherent is now pointless and can go away, and Luis helped
#       me writing a cocchinelle script and patch series to kill it, which I
#       think we should apply now just after -rc1 to finally settle these
#       issue"
