As a result of backporting a bugfix, virtio_net started passing void * to page_address, assuming that it will get silently converted to struct page *. But this does not happen on architectures where page_address is a macro, the result is build failure as the macro tries to dereference void*. Fix by reordering code slightly, so we always pass struct page * to page_address. Reported-by: Guenter
