Some virtio device drivers (9p) need to translate high virtual addresses to physical addresses, which are inserted into the virtqueue for processing by userspace. This patch exports the kmap_to_page symbol, so that the affected drivers can be compiled as modules.

Looks OK to me. Would generally prefer that an exported-to-modules symbol have some documentation, but I guess this one is obvious enough. Rusty, please include this if you grab the rest of the series.
