When objtool checked the fpu.o file, the following warnings appeared,
$ ./tools/objtool/objtool --orc arch/loongarch/kernel/fpu.o
arch/loongarch/kernel/fpu.o: warning: objtool: _save_fp_context() falls through
to next function fault()
This `fault` is only used in extable, it is not a function itself, and change
SYM_FUNC_START(fault) to the label method(.L_fault).
