Merge tag 'dma-mapping-5.3-1' of git://git.infradead.org/users/hch/dma-mapping
Pull dma-mapping fixes from Christoph Hellwig:
"Fix various regressions:
- force unencrypted dma-coherent buffers if encryption bit can't fit
into the dma coherent mask (Tom Lendacky)
- avoid limiting request size if swiotlb is not used (me)
- fix swiotlb handling in dma_direct_sync_sg_for_cpu/device (Fugang
Duan)"
* tag 'dma-mapping-5.3-1' of git://git.infradead.org/users/hch/dma-mapping:
dma-direct: correct the physical addr in dma_direct_sync_sg_for_cpu/device
dma-direct: only limit the mapping size if swiotlb could be used
dma-mapping: add a dma_addressing_limited helper
dma-direct: Force unencrypted DMA under SME for certain DMA masks
