Make it clearer what is going on by adding a function to go back from the "virtual" dma_addr to a kva and another to a struct page. This is used in the ib_uses_virt_dma() style drivers (siw, rxe, hfi, qib). Call them instead of a naked casting and virt_to_page() when working with dma_addr values encoded by the various ib_map functions. This also fixes the virt_to_page() casting problem Linus Walleij has been chasing.
