* MIPS: Replace add and sub instructions in relocate_kernel.S with addiuJames Cowgill2015-08-031-4/+4
| | | | | | | | | | | | | | | | | | | | 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 Signed-off-by: James Cowgill <James.Cowgill@imgtec.com> Cc: <stable@vger.kernel.org> # 4.0+ Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/10558/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
