Here is the summary with links:
  - [v3,1/2] riscv: allow kmalloc() caches aligned to the smallest value
    https://git.kernel.org/riscv/c/2926715163cf
  - [v3,2/2] riscv: enable DMA_BOUNCE_UNALIGNED_KMALLOC for !dma_coherent
    https://git.kernel.org/riscv/c/f51f7a0fc2f4

You are awesome, thank you!
