MIPS: ftrace: Add missing CONFIG_DYNAMIC_FTRACE
arch_ftrace_update_code and ftrace_modify_all_code are only available if CONFIG_DYNAMIC_FTRACE is selected. Fixes the following build problem on MIPS randconfig: arch/mips/kernel/ftrace.c: In function 'arch_ftrace_update_code': arch/mips/kernel/ftrace.c:31:2: error: implicit declaration of function 'ftrace_modify_all_code' [-Werror=implicit-function-declaration] Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Acked-by: Steven J. Hill <Steven.Hill@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/5435/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
