3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anton Blanchard <anton@samba.org>
commit 5d73320a96fcce80286f1447864c481b5f0b96fa upstream.
commit 8f9c0119d7ba (compat: fs: Generic compat_sys_sendfile implementation) changed the PowerPC 64bit sendfile call from sys_sendile64 to sys_sendfile.
Unfortunately this broke sendfile of lengths greater than 2G because sys_sendfile caps at MAX_NON_LFS. Restore what we had previously which fixes the bug.
