From f0263d2d222e9e25f2587e51a9dc58c6fb2a9352 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 19 Oct 2012 14:03:31 +0100 Subject: mm: highmem: export kmap_to_page for modules 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.
