Current status:
arch/mips/include/asm/ftrace.h:         ".section .fixup, \"ax\"\n"
         \
arch/mips/include/asm/ftrace.h:         ".section .fixup, \"ax\"\n"     \
arch/mips/include/asm/futex.h:          "       .section .fixup,\"ax\"
                 \n"     \
arch/mips/include/asm/futex.h:          "       .section .fixup,\"ax\"
                 \n"     \
arch/mips/include/asm/futex.h:          "       .section .fixup,\"ax\"
                         \n"
arch/mips/include/asm/futex.h:          "       .section .fixup,\"ax\"
                         \n"
arch/mips/include/asm/paccess.h:        ".section\t.fixup,\"ax\"\n"
                                 \
arch/mips/include/asm/paccess.h:        ".section\t.fixup,\"ax\"\n"
                                 \

So there are a few files which have spaces.
