Merge tag 'dma-mapping-5.8' of git://git.infradead.org/users/hch/dma-mapping
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
