Everyone: This series is a result of my attempt at changing the behaviour of dma_alloc_coherent() to guarantee that memory it returns is zeroed out. Mostly to avoid having to do that explicitly in driver code, but also to match behaviour that that function has in Linux. While working on that I noticed that there was a fair bit of MMU/DMA related code between ARM/ARM64 that can be shared, so I created a number of patches to do just that. Feedback is welcome!
