When building ARCH=h8300 defconfig: arch/h8300/kernel/traps.c: In function 'die': arch/h8300/kernel/traps.c:109:2: error: implicit declaration of function 'make_dead_task' [-Werror=implicit-function-declaration] 109 | make_dead_task(SIGSEGV); | ^~~~~~~~~~~~~~ arch/h8300/mm/fault.c: In function 'do_page_fault': arch/h8300/mm/fault.c:54:2: error: implicit declaration of function 'make_dead_task' [-Werror=implicit-function-declaration] 54 | make_dead_task(SIGKILL); | ^~~~~~~~~~~~~~ The function's name is make_task_dead(), change it so there is no more build error. Additionally, include linux/sched/task.h in arch/h8300/kernel/traps.c to avoid the same error because do_exit()'s declaration is in kernel.h but make_task_dead()'s is in task.h, which is not included in traps.c.
