Merge tag 'dma-mapping-5.18' of git://git.infradead.org/users/hch/dma-mapping
Pull dma-mapping updates from Christoph Hellwig: - do not zero buffer in set_memory_decrypted (Kirill A. Shutemov) - fix return value of dma-debug __setup handlers (Randy Dunlap) - swiotlb cleanups (Robin Murphy) - remove most remaining users of the pci-dma-compat.h API (Christophe JAILLET) - share the ABI header for the DMA map_benchmark with userspace (Tian Tao) - update the maintainer for DMA MAPPING BENCHMARK (Xiang Chen) - remove CONFIG_DMA_REMAP (me) * tag 'dma-mapping-5.18' of git://git.infradead.org/users/hch/dma-mapping: dma-mapping: benchmark: extract a common header file for map_benchmark definition dma-debug: fix return value of __setup handlers dma-mapping: remove CONFIG_DMA_REMAP media: v4l2-pci-skeleton: Remove usage of the deprecated "pci-dma-compat.h" API rapidio/tsi721: Remove usage of the deprecated "pci-dma-compat.h" API sparc: Remove usage of the deprecated "pci-dma-compat.h" API agp/intel: Remove usage of the deprecated "pci-dma-compat.h" API alpha: Remove usage of the deprecated "pci-dma-compat.h" API MAINTAINERS: update maintainer list of DMA MAPPING BENCHMARK swiotlb: simplify array allocation swiotlb: tidy up includes swiotlb: simplify debugfs setup swiotlb: do not zero buffer in set_memory_decrypted()
