  lib/scatterlist: cleanup macros into static inline functions (2021-12-22 09:21:43 +0100)

----------------------------------------------------------------
dma-mapping updates for Linux 5.17

 - refactor the dma-direct coherent allocator
 - turn an macro into an inline in scatterlist.h (Logan Gunthorpe)

----------------------------------------------------------------
Christoph Hellwig (11):
      dma-direct: factor out dma_set_{de,en}crypted helpers
      dma-direct: don't call dma_set_decrypted for remapped allocations
      dma-direct: always leak memory that can't be re-encrypted
      dma-direct: clean up the remapping checks in dma_direct_alloc
      dma-direct: factor out a helper for DMA_ATTR_NO_KERNEL_MAPPING allocations
      dma-direct: refactor the !coherent checks in dma_direct_alloc
      dma-direct: fail allocations that can't be made coherent
      dma-direct: warn if there is no pool for force unencrypted allocations
      dma-direct: drop two CONFIG_DMA_RESTRICTED_POOL conditionals
      dma-direct: factor the swiotlb code out of __dma_direct_alloc_pages
      dma-direct: add a dma_direct_use_pool helper
