* dma_inv_range(start, end)
*
* Invalidate (discard) the specified virtual address range.
* May not write back any entries. If 'start' or 'end'
* are not cache line aligned, those lines must be written
* back.
* - start - virtual start address
* - end - virtual end address
*
* dma_clean_range(start, end)
*
* Clean (write back) the specified virtual address range.
* - start - virtual start address
* - end - virtual end address
*
* dma_flush_range(start, end)
*
* Clean and invalidate the specified virtual address range.
