----------------------------------------------------------------
dma-mapping updates for 5.8, part 1

- enhance the dma pool to allow atomic allocation on x86 with AMD SEV
(David Rientjes)
- two small cleanups (Jason Yan and Peter Collingbourne)

----------------------------------------------------------------
David Rientjes (7):
dma-remap: separate DMA atomic pools from direct remap code
dma-pool: add additional coherent pools to map to gfp mask
dma-pool: dynamically expanding atomic pools
dma-direct: atomic allocations must come from atomic coherent pools
dma-pool: add pool sizes to debugfs
x86/mm: unencrypted non-blocking DMA allocations use coherent pools
dma-pool: scale the default DMA coherent pool size with memory capacity

Jason Yan (1):
dma-debug: make __dma_entry_alloc_check_leak() static

Peter Collingbourne (1):
dma-contiguous: fix comment for dma_release_from_contiguous
