[PATCH 00/12] ARM/ARM64 MMU code consolidation, zeroing of DMA coherent memory

2019-01-16 Thread Andrey Smirnov
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 not
