dma-mapping: remove unused map_page callback (2025-10-29 10:27:31 +0100)
----------------------------------------------------------------
dma-mapping updates for Linux 6.19:
- next part of DMA mapping API refactoring to physical addresses as the primary
interface instead of page+offset parameters; this time dma_map_ops callbacks
are converted to physical addresses, what in turn results also in some
simplification of architecture specific code (Leon Romanovsky and Jason
Gunthorpe)
- clarify that dma_map_benchmark is not a kernel self-test, but standalone
tool (Qinxin Xia)
----------------------------------------------------------------
Leon Romanovsky (14):
dma-mapping: prepare dma_map_ops to conversion to physical address
dma-mapping: convert dummy ops to physical address mapping
ARM: dma-mapping: Reduce struct page exposure in arch_sync_dma*()
ARM: dma-mapping: Switch to physical address mapping callbacks
xen: swiotlb: Switch to physical address mapping callbacks
dma-mapping: remove unused mapping resource callbacks
alpha: Convert mapping routine to rely on physical address
MIPS/jazzdma: Provide physical address directly
parisc: Convert DMA map_page to map_phys interface
powerpc: Convert to physical address DMA mapping
sparc: Use physical address DMA mapping
x86: Use physical address for DMA mapping
xen: swiotlb: Convert mapping routine to rely on physical address
dma-mapping: remove unused map_page callback
Qinxin Xia (2):
dma-mapping: benchmark: Restore padding to ensure uABI remained consistent
tools/dma: move dma_map_benchmark from selftests to tools/dma
