Subject: MIPS: unaligned: Fix build error on big endian R6 kernels
From: James Cowgill <James.Cowgill@xxxxxxxxxx>
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)
