3.14-stable review patch. If anyone has any objections, please let me know.

From: Max Filippov <jcmvbkbc@gmail.com>
commit 01e84c70fe40c8111f960987bcf7f931842e6d07 upstream.
xtensa actually uses sync_file_range2 implementation, so it should define __NR_sync_file_range2 as other architectures that use that function. That fixes userspace interface (that apparently never worked) and avoids special-casing xtensa in libc implementations. See the thread ending at http://lists.busybox.net/pipermail/uclibc/2015-February/048833.html for more details.
