The correct order is: swiotlb: make is_buffer_dma_capable architecture-specific swiotlb: make range_needs_mapping architecture-specific swiotlb/xen: update xen for swiotlb_arch_force_mapping changes swiotlb: make swiotlb allocation functions architecture-specific swiotlb/xen: update xen for changes to swiotlb allocation interface swiotlb: make swiotlb phys<->bus translations architecture-specific swiotlb/xen: update xen swiotlb for phys<->bus API changes xen: remove arch/x86/xen/pci-swiotlb.c Also xen-devel missed out due to a typo, sorry.
