[PATCH v2 1/3] mm: highmem: export kmap_to_page for modules

[Will Deacon]

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.
