Pull dma-mapping updates from Christoph Hellwig: - enhance the dma pool to allow atomic allocation on x86 with AMD SEV (David Rientjes) - two small cleanups (Jason Yan and Peter Collingbourne) * tag 'dma-mapping-5.8' of git://git.infradead.org/users/hch/dma-mapping: dma-contiguous: fix comment for dma_release_from_contiguous dma-pool: scale the default DMA coherent pool size with memory capacity x86/mm: unencrypted non-blocking DMA allocations use coherent pools dma-pool: add pool sizes to debugfs dma-direct: atomic allocations must come from atomic coherent pools dma-pool: dynamically expanding atomic pools dma-pool: add additional coherent pools to map to gfp mask dma-remap: separate DMA atomic pools from direct remap code dma-debug: make __dma_entry_alloc_check_leak() static
