#     
#     Pull dma-maping updates from Christoph Hellwig:
#     
#      - allow dynamic sizing of the swiotlb buffer, to cater for secure
#        virtualization workloads that require all I/O to be bounce buffered
#        (Petr Tesarik)
#     
#      - move a declaration to a header (Arnd Bergmann)
#     
#      - check for memory region overlap in dma-contiguous (Binglei Wang)
#     
#      - remove the somewhat dangerous runtime swiotlb-xen enablement and
#        unexport is_swiotlb_active (Christoph Hellwig, Juergen Gross)
#     
#      - per-node CMA improvements (Yajun Deng)

#     * tag 'dma-mapping-6.6-2023-08-29' of git://git.infradead.org/users/hch/dma-mapping:
#       swiotlb: optimize get_max_slots()
#       swiotlb: move slot allocation explanation comment where it belongs
#       swiotlb: search the software IO TLB only if the device makes use of it
#       swiotlb: allocate a new memory pool when existing pools are full
#       swiotlb: determine potential physical address limit
#       swiotlb: if swiotlb is full, fall back to a transient memory pool
#       swiotlb: add a flag whether SWIOTLB is allowed to grow
#       swiotlb: separate memory pool data from other allocator data
#       swiotlb: add documentation and rename swiotlb_do_find_slots()
#       swiotlb: make io_tlb_default_mem local to swiotlb.c
#       swiotlb: bail out of swiotlb_init_late() if swiotlb is already allocated
#       dma-contiguous: check for memory region overlap
#       dma-contiguous: support numa CMA for specified node
#       dma-contiguous: support per-numa CMA for all architectures
#       dma-mapping: move arch_dma_set_mask() declaration to header
#       swiotlb: unexport is_swiotlb_active
#       x86: always initialize xen-swiotlb when xen-pcifront is enabling
#       xen/pci: add flag for PCI passthrough being possible
