Subject: [PATCH] MIPS: Replace add and sub instructions in relocate_kernel.S
 with addiu

Fixes the assembler errors generated when compiling a MIPS R6 kernel with
CONFIG_KEXEC on, by replacing the offending add and sub instructions with
addiu instructions.

Build errors:
arch/mips/kernel/relocate_kernel.S: Assembler messages:
arch/mips/kernel/relocate_kernel.S:27: Error: invalid operands `dadd $16,$16,8'
arch/mips/kernel/relocate_kernel.S:64: Error: invalid operands `dadd $20,$20,8'
arch/mips/kernel/relocate_kernel.S:65: Error: invalid operands `dadd $18,$18,8'
arch/mips/kernel/relocate_kernel.S:66: Error: invalid operands `dsub $22,$22,1'
scripts/Makefile.build:294: recipe for target 'arch/mips/kernel/relocate_kernel.o' failed
