This patch introduces a global pointer, dma_ops, which points to an appropriate dma_mapping_ops that the kernel should use. This is a common way to handle multiple dma_mapping_ops (X86, POWER, and SPARC). dma_ops is set in platform_dma_init. We also set it by hand where machvec_init is callev via subsys_initcall. - IA64_DIG_VTD uses vtd_dma_ops. - IA64_HP_ZX1 uses sba_dma_ops. - IA64_HP_ZX1_SWIOTLB uses hwsw_dma_ops. - IA64_SGI_SN2 uses sn_dma_ops. - The rest use swiotlb_dma_ops.
