commit ab4ababdf77ccc56c7301c751dff49c79709c51c upstream.
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.
Fixes: 0e25498f8cd4 ("exit: Add and use make_task_dead.")
