Pull dma-mapping updates from Christoph Hellwig:
- fix a PageHighMem check in dma-coherent initialization (Doug Berger)
- clean up the coherency defaul initialiation (Jiaxun Yang)

* tag 'dma-mapping-6.4-2023-04-28' of git://git.infradead.org/users/hch/dma-mapping:
swiotlb: Omit total_used and used_hiwater if !CONFIG_DEBUG_FS
swiotlb: track and report io_tlb_used high water marks in debugfs
swiotlb: fix debugfs reporting of reserved memory pools
swiotlb: relocate PageHighMem test away from rmem_swiotlb_setup
of: address: always use dma_default_coherent for default coherency
dma-mapping: provide CONFIG_ARCH_DMA_DEFAULT_COHERENT
dma-mapping: provide a fallback dma_default_coherent
dma-debug: Use %pa to format phys_addr_t
dma-debug: add cacheline to user/kernel space dump messages
dma-debug: small dma_debug_entry's comment and variable name updates
dma-direct: cleanup parameters to dma_direct_optimal_gfp_mask
