Linus Torvalds 9e3a25dc99 dma-mapping updates for Linux 5.3 
- move the USB special case that bounced DMA through a device
    bar into the USB code instead of handling it in the common
    DMA code (Laurentiu Tudor and Fredrik Noring)
  - don't dip into the global CMA pool for single page allocations
    (Nicolin Chen)
  - fix a crash when allocating memory for the atomic pool failed
    during boot (Florian Fainelli)
  - move support for MIPS-style uncached segments to the common
    code and use that for MIPS and nios2 (me)
  - make support for DMA_ATTR_NON_CONSISTENT and
    DMA_ATTR_NO_KERNEL_MAPPING generic (me)
  - convert nds32 to the generic remapping allocator (me)
