    Merge branch 'stable/for-linus-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb
    
    Pull swiotlb updates from Konrad Rzeszutek Wilk:
     "A new feature called restricted DMA pools. It allows SWIOTLB to
      utilize per-device (or per-platform) allocated memory pools instead of
      using the global one.
    
      The first big user of this is ARM Confidential Computing where the
      memory for DMA operations can be set per platform"
