Merge tag 'dma-mapping-5.3' of git://git.infradead.org/users/hch/dma-mapping
Pull dma-mapping updates from Christoph Hellwig:
- 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)
