[PATCH] frv: implement and export various things required by modules
Export a number of features required to build all the modules. It also implements the following simple features: (*) csum_partial_copy_from_user() for MMU as well as no-MMU. (*) __ucmpdi2(). so that they can be exported too. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
