This reverts commit 65688d2a05deb9f0671a7e2301eadbfe7e27c9e9. Unfortunately, the original Qualcomm Kryo cores integrated into the MSM8996 SoC feature an L2 cache with 128-byte lines which sits above the Point of Coherency. Consequently, we must restore ARCH_DMA_MINALIGN to its former ugly self so that non-coherent DMA can be performed safely on devices built using this SoC. Thanks to Jeffrey Hugo for confirming this with a hardware designer.
