This single patch adds explicit cache maintenance (flush/invalidate) for fastrpc argument buffers on platforms that lack DMA coherency between the CPU and DSP. The intent is sound — non-coherent platforms need software cache management — but the implementation has a **critical correctness bug** in the invalidation path (mismatched DMA direction in `dma_buf_end_cpu_access`), ignores error returns from the dma-buf API, and uses a somewhat unconventional cache-maintenance pattern that deserves closer scrutiny.
**Verdict: Needs revision before merge.**
