Subject: [PATCH 4.1 01/84] MIPS: unaligned: Fix build error on big endian R6 kernels

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

------------------

From: James Cowgill <James.Cowgill@...tec.com>

commit 531a6d599f4304156236ebdd531aaa80be61868d upstream.

Commit eeb538950367 ("MIPS: unaligned: Prevent EVA instructions on kernel
unaligned accesses") renamed the Load* and Store* defines in unaligned.c
to _Load* and _Store* as part of its fix. One define was missed out which
causes big endian R6 kernels to fail to build.

arch/mips/kernel/unaligned.c:880:35:
error: implicit declaration of function '_StoreDW'
 #define StoreDW(addr, value, res) _StoreDW(addr, value, res)
                                   ^
