Linus Torvalds 66c56cfa64 remove dma_zalloc_coherent
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.
