  dma-mapping: add missing `inline` for `dma_free_attrs` (2026-03-25 08:01:21 +0100)

----------------------------------------------------------------
dma-mapping fixes for Linux 7.0

A set of fixes for DMA-mapping subsystem, which resolve false-positive
warnings from KMSAN and DMA-API debug (Shigeru Yoshida and Leon
Romanovsky) as well as a simple build fix (Miguel Ojeda).

----------------------------------------------------------------
Leon Romanovsky (8):
      dma-debug: Allow multiple invocations of overlapping entries
      dma-mapping: handle DMA_ATTR_CPU_CACHE_CLEAN in trace output
      dma-mapping: Clarify valid conditions for CPU cache line overlap
      dma-mapping: Introduce DMA require coherency attribute
      dma-direct: prevent SWIOTLB path when DMA_ATTR_REQUIRE_COHERENT is set
      iommu/dma: add support for DMA_ATTR_REQUIRE_COHERENT attribute
      RDMA/umem: Tell DMA mapping that UMEM requires coherency
      mm/hmm: Indicate that HMM requires DMA coherency

Miguel Ojeda (1):
      dma-mapping: add missing `inline` for `dma_free_attrs`

Shigeru Yoshida (1):
      dma: swiotlb: add KMSAN annotations to swiotlb_bounce()
