Implement ion_cma_unmap_kernel, ion will call it unconditionally. Use correct gfp flags when calling dma_alloc_coherent so it doesn't try to use atomic DMA memory. Check for invalid alignment when allocating. Reject cached allocations - the cpu address returned by dma_alloc_coherent is always going to be an uncached mapping, so map_kernel will not see data written by a cached userspace mapping.
