So there is some support module needed? Which contains kunmap_high()?

BTW, if you delete all references to nbd_rw_iovec in the code, the
kunmap problem should go away. It seems to be used in the raw device
interface that I added for fun ... maybe I should add an ifdef.

Where highmem_start_page comes from, I don't know.
