fad6a029c4 remove dma operations in struct ia64_machine_vector
We don't need dma operation hooks in struct ia64_machine_vector
now. This also removes unused ia64_mv_dma_* typedefs.

62fdd7678a [IA64] Add Variable Page Size and IA64 Support in Intel IOMMU
The patch contains Intel IOMMU IA64 specific code. It defines new
machvec dig_vtd, hooks for IOMMU, DMAR table detection, cache line flush
function, etc.

For a generic kernel with CONFIG_DMAR=y, if Intel IOMMU is detected,
dig_vtd is used for machinve vector. Otherwise, kernel falls back to
dig machine vector. Kernel parameter "machvec=dig" or "intel_iommu=off"
can be used to force kernel to boot dig machine vector.
