    Linus Torvalds authored
    Pull dma-mapping updates from Christoph Hellwig:
     - replace the force_dma flag with a dma_configure bus method. (Nipun
       Gupta, although one patch is іncorrectly attributed to me due to a
       git rebase bug)
     - use GFP_DMA32 more agressively in dma-direct. (Takashi Iwai)
     - remove PCI_DMA_BUS_IS_PHYS and rely on the dma-mapping API to do the
       right thing for bounce buffering.
     - move dma-debug initialization to common code, and apply a few
       cleanups to the dma-debug code.
     - cleanup the Kconfig mess around swiotlb selection
     - swiotlb comment fixup (Yisheng Xie)
     - a trivial swiotlb fix. (Dan Carpenter)
     - support swiotlb on RISC-V. (based on a patch from Palmer Dabbelt)
     - add a new generic dma-noncoherent dma_map_ops implementation and use
       it for arc, c6x and nds32.
     - improve scatterlist validity checking in dma-debug. (Robin Murphy)
     - add a struct device quirk to limit the dma-mask to 32-bit due to
       bridge/system issues, and switch x86 to use it instead of a local
       hack for VIA bridges.
     - handle devices without a dma_mask more gracefully in the dma-direct
