Arnd Bergmann eb74618013 riscv: dma-mapping: only invalidate after DMA, not flush ... No other architecture intentionally writes back dirty cache lines into a buffer that a device has just finished writing into. If the cache is clean, this has no effect at all, but if a cacheline in the buffer has actually been written by the CPU, there is a driver bug that is likely made worse by overwriting that buffer.
