Ive just picked up the bits required for RISC-V unification of cache flushing. Remaining patches from the series [0] will be taken care by Arnd soon. * b4-shazam-merge: riscv: dma-mapping: switch over to generic implementation riscv: dma-mapping: skip invalidation before bidirectional DMA riscv: dma-mapping: only invalidate after DMA, not flush Link: https://lore.kernel.org/r/20230816232336.164413-1-prabhakar.mahadev-lad.rj@bp.renesas.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
