[ARM] 3737/1: Export ARM copy/clear_user_page symbols
Patch from George G. Davis As reported by various folks on the ARM Linux kernel mailing list, the video-buf.ko driver has undefined references on all ARM machines which use it as observed during `make modules`: Warning: "v4wb_clear_user_page" [drivers/media/video/video-buf.ko] undefined! Similar warnings exist for all ARM machines which use this driver. So this change adds the missing EXPORT_SYMBOLs to allow using this driver as a module. Signed-off-by: George G. Davis <gdavis@mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
